About this worksheet

What students practice

Students sort shapes by whether they have parallel sides and whether they have right angles.
Students count right, acute, and obtuse angles in shapes and classify triangles by their angles.
Students pick shapes that match a rule about parallel sides and angles, and explain why.

How to use

Give students the corner of an index card to test for right angles and a ruler to extend sides when checking for parallel sides. Part 2 works well as partner talk.

Tile Orders at the Mosaic Shop

Sort tiles by parallel sides, right angles, and angle types.

Part 1: Check each tile

Parallel sides would never meet, even if you made them longer. Perpendicular sides meet to make a right angle, which is a square corner. An acute angle is smaller than a right angle. An obtuse angle is bigger than a right angle.

Mr. Okafor needs a border tile with exactly 1 pair of parallel sides. Which tile should he pick?
