Question

A dilation is applied to a triangle such that the sides of the image are 1.5 times the length of their corresponding sides in the original triangle. Then the angles of the image must be 1.5 times the size of the corresponding angles in the original triangle.

Answer 1

The angles in the new triangle is the same as the original triangle.

The angles are the same, they are not multiplied by the factor of 1.5

Answer 2

Angles remain unchanged.

Explanation:

When a dilation is applied to a triangle such that the sides of the image are 1.5 times the length of their corresponding sides in the original triangle.

After dilation both the triangles remains similar. Their corresponding sides get dilated but the corresponding angles remain unchanged.
