Answer:
more ... The same shape and size, but we are allowed to flip, slide or turn. In this example the shapes are congruent (you only need to flip one over and move it a little). Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.

Answer:wow this is hard
Step-by-step explanation:
Using distributive property, we get:
3x-9=0
3x=9
x=3
So, x=3. Now that was easy, huh? :)
I underlined the numbers you needed
Answer:
b= 70
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to exterior angle.
a+b = 140
We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal
b+b = 140
2b =140
Divide by 2
2b/2 =140/2
b= 70
