Description

Rotating a Figure 180 Degrees Clockwise

Introduction

A 180-degree clockwise rotation turns a figure halfway around a fixed point. Rotations are useful in geometry and can also be seen in spinning objects, designs, games, and animations. Learning rotations ...

Transcript

Emma is working on a problem in which she needs to rotate trapezoid WXYZ 180 degrees clockwise about the origin in the coordinate plane.

She starts by listing the coordinates for each vertex, which are (-4, 2) for W, (-3, 4) for X, (-1, 4) for Y, and (-1, 2) for Z.

To rotate the figure, Emma uses the 180-degree rotation rule.
