Congruent
The same shape and size.
Two shapes are congruent when you can Turn, Flip and/or Slide one so it fits exactly on the other.
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.
20+8(q-11)=-12
20+8q-8•11=-12
20+8q-88=-12
-68+8q=-12 add 68
+68 +68
8q=-12+68
8q=56 divide by 8
/8 /8
q=56/8
q=7 solved for q
