    • Teacher's Instruction
    1. Teachers should review the sides and angles of basic geometric shapes before beginning this exercise.
    2. Use these exercises to reinforce students' understanding of basic shapes and the relationship between side lengths and angles. Challenge students to draw a rhombus or parallelogram. Encourage them to draw different types of triangles, not just equilateral triangles. If students are familiar with the Pythagorean Theorem, they can try drawing a right triangle and calculating its hypotenuse.
    3. Points to Ponder: Observe that to draw a regular polygon with N sides, you will need to turn 360/N degrees. Why? The sum of the interior angles of a N sided polygon will always be (N-2) * 180 starting with triangles and quadrilaterals. You can help students understand that.
