Identifying Congruent Figures

This lesson teaches how to identify congruent figures by comparing their segments and angles. It explains that congruence in geometry means having the same length, measure, or size. The lesson clarifies common misunderstandings about congruence, emphasizing that congruent figures must be the same size and shape. Examples are provided to illustrate congruent segments, angles, and figures, highlighting the importance of corresponding parts.
