A Rotation of 270° About the Origin (Mathematics Lesson)

A 270° Rotation About the Origin

A rotation is described by the angle the shape turns about a center of rotation.



The shape above has been rotated 270° clockwise (the angle of reflection) about the origin (0, 0) (the center of rotation).

Real Examples of a Rotation of 270° About the Origin

All of the following shapes have been rotated by 270° clockwise about the origin:

Top Tip
270° IS THREE QUARTER TURNS

270° is three quarter turns.



Note
WHAT IS A ROTATION?

A rotation turns a shape around a center.

A rotation is a type of transformation.

HOW TO THINK OF ROTATIONS OF 270° ABOUT THE ORIGIN

Imagine a shape is drawn on a pair of axes on a sheet of paper...



Imagine sticking a pin through the origin and into a surface.



If you span the paper around, the pin would stay in place and every other point on the paper would turn in a circle around it.

By turning the paper a three quarter turns, a 270° rotation about the origin will take place.
