Explore the Interior Angles of Shapes

Once your students have an understanding of acute, right and obtuse angles, the next step is being able to identify these angles in common two-dimensional shapes such as triangles, squares, pentagons, hexagons and octagons.

In regular shapes, all interior angles are the same size. This differentiated maze-inspired worksheet has been designed to help your students review the interior angles of regular polygons. Students are required to find their way through the maze by correctly answering questions, such as:

• What is the sum of all the interior angles in a triangle?
• What types of angles are found in a square?
• How many angles does an octagon have?

Students start at the “Start Here” box. They then color a path through the maze to the “End Here” box by correctly answering the questions.

The resource download includes:

• 2 x maze worksheets (one easier, one more challenging)
• 2 x answer keys.

To make it easier for teachers to identify the two differentiated versions (but not so obvious to the students!), a dot system has been used. The harder version of the worksheet has two dots in the top right corner of the worksheet. The easier version has one dot in this same position.
