This math topic focuses on estimating angles in degrees, specifically comparing a given angle to estimate a second angle. This skill is an essential part of the Geometry - Angle Basics unit. Students are presented with illustrations and must choose the closest estimate from multiple choices. The progression of questions is designed to reinforce a practical understanding of angle estimation, pivotal for developing spatial reasoning and geometry skills.
