If a triangle is rotated 90° clockwise, what happens to its orientation?

Back

The triangle's orientation changes, and its vertices move to new positions based on the rotation.

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips a figure over a line.

How do you determine the new coordinates of a point after a rotation?

Back

To find the new coordinates, apply the rotation rules based on the angle and direction of rotation.
