Question

Triangle ABC has a perimeter of 25 meters. It is translated 10 meters to the left and then rotated 90° counterclockwise about vertex A. What will be the perimeter of the resulting figure?

Answer 1

25

Explanation:

After translating and rotating the triangle, the perimeter of the resulting figure will remain the same at 25 meters. Translation and rotation do not change the lengths of the sides, so the perimeter remains constant.
