Rotations of triangles about the origin worksheets

What is on this worksheet

A triangle is turned 90 degrees clockwise, 90 degrees counter-clockwise or 180 degrees about the origin, and students write its new corners.

• Transformation: Rotation about the origin

You can change any of these settings above. Press "New problems" for a fresh set with the same settings, or pick Version A to Z to print different sheets for neighboring desks. The answer key always matches.

About translations, reflections and rotations

A shape is drawn on a four-quadrant grid with its corners lettered. A rule says how to move it: translate by a number of units, reflect over the x-axis or y-axis, or rotate 90 degrees either way or 180 degrees about the origin. Students write the new coordinates of each corner.

Every image stays on the grid. Choose one kind of transformation or a mix, triangles or quadrilaterals, and the grid size. The answer key draws the image and writes its coordinates.

Printing
