Question

a triangle with a perimeter of 13 centimeters is rotated and reflected in the coordinate plane. what is the perimeter of the resulting image? enter your answer in the box.

Explanation:

Step1: Recall transformation properties

Rotations and reflections are rigid - motions. Rigid - motions preserve the shape and size of a figure.

Step2: Determine perimeter of image

Since the perimeter of the original triangle is 13 cm and rigid - motions do not change the lengths of the sides of a figure, the perimeter of the resulting image is the same as the perimeter of the original figure.

Answer:

13
