- After reviewing types of angles and how to measure angles using a protractor, students will see how many triangles they can construct using an 18-foot beam. Through this activity, students will discover the conditions that must be met to construct a triangle. For example, the sum of the lengths of two sides of a triangle must be greater than the longest side of the triangle. They will also discover that the sum of the angles of a triangle is always 180 degrees.
