Sum of Inside Angles on a Shape (Level 3)

This math topic focuses on calculating the sum of inside angles of various shapes, which is an essential aspect of geometry involving angles and transformations. Participants are required to apply their knowledge of geometric properties to determine the cumulative measure of angles within diverse polygons presented in a series of questions. Each problem presents a unique shape and multiple-choice answers, challenging the learners to choose the correct sum of the internal angles. This exercise enhances geometric intuition and angle calculation skills.
