The answer to #4 is A equilateral because all the sides are the same. the sides are equal.
7 would be c, 45 you have to make sure the sum is 180 #8 is B the same goes for that on fill in x and y. #11 isD And # 12 is c the sum must be 180.

The triangle with sides of 9, 9, and 9 is equilateral (Option A). The measure of angle 4 is 45 degrees (Option C) when angle 7 is 135 degrees. To ensure parallel lines for the other questions, the values of x and y are 68 and 72 respectively (Option A), the lines are confirmed to be parallel (Option B), and x is 64 (Option C).
