Question

A triangle is rotated 35 degrees about the origin. Which of the following statements is true about the realationship between the image and the pre- image

Answer 1

Below are the choices and the answer for me is A.

a. The lengths of the sides and the measures of the angles are preserved, so the triangle are congruent
b. The lengths of the sides are enlarged and measures of the angles are preserved, so the triangles are similar.
c. The lengths of the sides change and the measures of the angles change as well, so the triangles look nothing alike.
d. The lengths of the sides are reduced and measures of the angles are preserved, so one triangle is reduction of the other.
