Question

question 8 of 10
dilating a triangle changes the angles and side length of the triangle.
a. true
b. false

Explanation:

Dilation is a transformation that scales a figure by a scale factor. When a triangle is dilated, the side lengths change (they are multiplied by the scale factor), but the angles remain the same because dilation preserves the shape (it is a similarity transformation). So the statement that dilating a triangle changes the angles is incorrect.

Answer:

B. False
