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.

1. Brand A scooter has a top speed that goes 2 miles per hour faster than Brand B. If after 3 hours, Brand A scooter traveled 24 miles at its top speed, at what rate did Brand B scooter travel at its top speed if it traveled the same distance? Write an equation to determine the solution. Identify the if-then moves used in your solution.
Answer:
6 miles/hr
Step-by-step explanation:
Given:
Top speed of Brand A scooter goes 2 miles per hour faster than Brand B.
Distance traveled by brand A scooter on its top speed in 3 hours = 24 miles
To find:
The rate at which brand B traveled the same distance at its top speed ?
Solution:
Let the top speed/rate of brand B scooter = [tex]x[/tex] miles/hr
According to question:
Top speed/rate of brand A scooter = [tex]x+2[/tex] miles/hr
Formula:
[tex]Distance = Speed \times Time[/tex]
Distance is given to be equal to 24 miles:
24 = ([tex]x+2[/tex]) [tex]\times 3[/tex] ...... (1)
Solving the above equation by first dividing the equation on both sides with 3:
[tex]\dfrac{24}{3} = \dfrac{(x+2)\times 3}{3}\\\Rightarrow 8 = (x+2)[/tex]
Now subtracting 2 from both the sides:
[tex]\Rightarrow 8-2=x+2-2\\\Rightarrow x=6\ miles/hr[/tex]
Therefore, the answer is:
Top speed of scooter B is 6 miles/hr.
The if-then moves used to solve the equation (1) are:
Dividing by a non zero number on both sides, then subtracting a number on both sides.

What is an equation of the line that passes through the point ( 8 , − 4 ) and is parallel to the line x − 4 y = 12 x−4y=12?
Answer:
as the line is parallel we do not change x-4y what we change is the result x = 8 & y = -4 so the result is 8 - 4 (-4) = 24 so the equation is 24

A
A. 112
B. 120
C. 105
D. 126
Answer:it’s 126
Step-by-step explanation:
The length of AC will be 126. Option D is correct. Similarity of the triangle is applied to find the value of AC.
What is SAS similarity theorem?ΔABC ~ ΔDEF only if ratio of two sides of ΔABC and corresponding two sides of ΔDEF is equal, and the angle included in both sides are congruent.
Suppose the two sides of ΔABC are AB and BC, and that of DEF be DE and EF, then for SAS similarity, we need
From the similarity of the triangle;
[tex]\rm \frac{AB}{ED} =\frac{AC}{EC} \\\\ \rm \frac{81}{9} =\frac{140-x}{x} \\\\ 9x=140-x\\\\ 10x=140 \\\\ x=14[/tex]
The measure of AC is;
AC=140-x
AC=140-14
AC=126
The length of AC will be 126.
Hence,option D is correct.

-3x + 2c = -3, solve for x
Answer:
x=2c/3+1
Step-by-step explanation:
Subtract 2c from both sides.
−3x=−3−2c
The equation is in standard form.
−3x=−2c−3
Divide both sides by −3.
-3x/-3=-2c-3/-3
Dividing by −3 undoes the multiplication by −3.
x=-2c-3/-3
Divide −3−2c by −3.
x=2c/3+1

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. If Shawn knows that the slope of the line is 4 and the line passes through the point (1,8), which equation should be use to find the y-intercept and what is the y-intercept of the line?
Answer:
y = 4x + 4
Step-by-step explanation:
Plug in your x and y coordinates
8 = 4(1) + b
8 = 4 + b get your constants together by subtracting 4 from both sides
4 = b

Answer: Choose which answer you think fits
Step-by-step explanation:
The roots are there to confuse you. They have the exact same numbers under the radical, so you can treat it like a variable and add 4 + 3 since theyre like terms.
[tex]7(5\sqrt{x2y} ) = 35\sqrt{x2y}[/tex]
If that's an x^2, bring the x out and keep the y inside the radical to get:

Can you map shape I onto shape II by a sequence of transformations? If so, give a sequence of transformations that maps shape I onto shape II.
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 is the equation of the line passing through the points (3,6) and (2,10)
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.
Equation of the line: y=-4x+18
