Question

question 8 of 10 what degree of rotation about the origin will cause the triangle below to map onto itself? a. 360° b. 180° c. 90° d. 270°

Explanation:

Step1: Recall rotation property

A full - rotation is 360°.

Step2: Understand mapping onto itself

When a shape is rotated 360° about a point (in this case the origin), it returns to its original position, mapping onto itself. A 180° rotation flips the shape across the center of rotation, a 90° and 270° rotation changes the orientation of the shape. Only a 360° rotation will result in the triangle returning to its exact starting position.

Answer:

A. 360°
