What is Congruency

Triangles that are identical in size and shape are said to be congruent triangles. Inferred from this is that the matching sides and angles are equal. Without checking each of the triangles' sides and angles, we can determine whether the two triangles are congruent.

Rule of Congruency:

1- SAS (Side-Angle-Side): Two triangles are congruent if two sides and the included angle of one triangle are equal to the two sides and the included angle of the other triangle.

2- ASA (Angle-Side-Angle): Two triangles are congruent if two triangles and the included side of one triangle are equal to two angles and the included side of the other triangle.

3- AAS (Angle-Angle-Side): Two triangles are congruent if any two pairs of angles and one pair of corresponding sides are equal.

4- SSS (Side-Side-Side): If three sides of one triangle are equal to the three sides of another triangle, then the two triangles are congruent.

5- RHS (Right angle- Hypotenuse-Side): If in two right triangles the hypotenuse and one side of one triangle are equal to the hypotenuse and one side of the other triangle, then the two triangles are congruent.

Since JK= QP
KL= KR
Angle LKJ= Angle QRP

So Δ LKJ ≅ Δ QRP.

Answers

Answer:

Step-by-step explanation:

Let the consecutive even integers be 2n and 2n+2.

lesser integer = 2n

Greater integer = 2n+2

If twice the lesser of two integers is 4 less than two times the greater integer, this is expressed mathematically as;

2(less integer) = 2(greater integer) - 4

Substituting the given integers;

2(2n) = 2(2n+2)-4

2(2n) = 2[(2n+2)-2]

2n = 2n+2-2

2n = 2n

2 = 2

This two values cancels out and become 0 = 0. This equality shows that it is an identity pair and it is true for all even integers.

The sum of the digits of two number is 7. The product

is 976. find the number.

Answers

Answer:

awd

Step-by-step explanation:

The given conditions can be satisfied by the numbers 16 and 61.

What is place value?

The foundation of our entire number system is place value. In this approach, the value of a digit in a number is determined by where it appears in the number.

Given, The sum of the digits of two numbers is 7. The product the number and its reverse number are formed by Interchanging the digits is 976.

Let "xy" be the given two-digit number.

Thus,

x +y =7....(1)

and (10x+y)(10y + x) = 976

100xy + 10y² + 10x² + xy = 976

101xy + 10y² + 10x² = 976

From equation 1

707x - 101x² + 490 +10x² - 140x + 10x² = 976

-81x² + 567x = 486

x² - 7x + 6 = 0

Thus x = 1, 6

y = 6,1

Therefore, The number that satisfies the given conditions is 16 or 61.

Point H is between G and I. If HG = 8x + 7, HI = 3x - 2, and GI = 38, what would be the length of GH ?

Answers

Answer:

let's see what to do...

Step-by-step explanation:

H is between G and I.

G I = G H + H I

38 = 8 x + 7 + 3x - 2

38 = 11 x + 5

subtract the sides of equation minus 5

38 - 5 = 11 x + 5 - 5

33 = 11 x

divided the sides of equation by 11

33 ÷ 11 = 11 x ÷ 11

3 = x

So the lenght of (G H) is :

8 x + 7 -----¢ 8 (3) + 7 = 24 + 7 = 31

And we're done.

Thanks for watching buddy good luck.

Answer: y= - 4x+18

Step-by-step explanation:

Equation: y=mx+b

***remember: b is the y-intercept and m is the slope.

m=[tex]\frac{y2-y1}{x2-x1}[/tex]

3= x1

2= x2

6= y1

10=y2

m=[tex]\frac{10-6}{2-3}[/tex]= [tex]\frac{4}{1}[/tex]= -4

m=-4

Now we have y=-4x+b , so let's find b.

You can use either (x,y) such as (3,6) or (2,10) point you want..the answer will be the same:

   (3,6). y=mx+b or 6=-4 × 3+b, or solving for b: b=6-(-4)(3). b=18.

   (2,10). y=mx+b or 10=-4 × 2+b, or solving for b: b=10-(-4)(2). b=18.

Yes, the shape I can onto shape II by a sequence of transformations.

Two images are given we have to determine that whether any of shape can onto other shapes.

What is a graph?

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The shape I can be mapped into shape II through a series of transformations.

The first sequence would involve translating shape I 8 units up and 4 units left, reflecting shape I across the x-axis, then rotating shape I 90 degrees counterclockwise about the origin.

Therefore, the shape I can onto shape II by a sequence of transformations.

What integer is equal to |-10| + |-20|

Please answer

Answers

Answer:

30

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| - 10 | + | - 20 |

= 10 + 20

= 30

Answer:

|-10| + |-20| = 30

Step-by-step explanation:

Absolute Value

The absolute value of x, written |x| is a positive number that represents the distance from the origin and the number.

In practice, the absolute value is found writing the number without the negative sign, if present.

For example:

|-9| = 9

|76| = 76

|0| = 0

The given expression is

|-10| + |-20|

Calculate each absolute value separately:

|-10|=10

|-20|=20

Thus:

|-10| + |-20| = 10+20 = 30

|-10| + |-20| = 30

which of the following is NOT a perfect squareanswer any other questions on the sheet if possible please! will give brainliest Filmmaking is about control. The screenwriter controls the story. The director controls the actors. The camera operator controls what the audience sees. However, one element that is very difficult to control is sound. If a film is being made outdoors, a noisy plane might fly overhead. A flock of geese might start squawking. An actor's stomach could grumble during a take. Worse, the footsteps of the filmmakers might be heard off-camera. All of these things can ruin a film's sound. This is why films use Foley artists. Foley artists improve film sound by recreating it in a soundproof studio. They record themselves making footsteps and opening doors. They jingle keys in their pockets. They sit in old creaking chairs. These sounds are then used to replace the unwelcome sounds that were captured during filmmaking. Foley sound was named after Jack Foley, who was born in 1891. Jack developed sound tricks that many filmmakers still use today. For example, he moved a cloth around in his pocket to mimic the sound of actors moving around. Foley sound recording can be physically demanding. If a film showed an actor running and jumping, this probably meant the Foley artist had to run and jump, too. Foley artist Dustin DuPilka, who recorded sounds for the movie Men in Black, said, "If there's a lot of running in a certain [scene], you have to get ready to sweat all day." Foley sound recording also requires a lot of creative thinking. Artists go to great lengths to get the perfect sound. For example, in the movie E.T., a Foley artist used a wet T-shirt stuffed with Jell-O for E.T.'s walk. In the movie Ice Age, a huge log was dropped into a pit of mud to create the mammoth's footsteps. The next time you watch a film, listen carefully. Chances are that much of what you are hearing was created by a Foley artist.5The author says that Foley sound recording requires a lot of creative thinking. The author supports this idea by A. including step-by-step instructions so readers can record their own Foley sound. B. presenting facts about films that were made without the use of Foley sound. C. giving examples of creative sound effects that were used in popular movies.
