Understanding Congruent Triangles

This lesson covers congruent triangles, explaining that congruent means identical in shape and size. It discusses the properties of congruent triangles, including equal angles and sides, and how to identify them by overlaying. The difference between congruent and similar triangles is highlighted, emphasizing that congruent triangles are identical in every way. The lesson also introduces the symbol for congruence and explains that corresponding sides and angles are equal in congruent triangles. Finally, it applies these concepts to example problems.

What does the term 'congruent' imply when referring to triangles?

• Same shape but different size

• Same size but different shape

• Exactly the same in shape and size

• Different in both shape and size

How many sets of equal angles do congruent triangles have?

• Two sets

• Four sets

• One set

• Three sets

What is a key characteristic of congruent triangles?

• They can have different angles

• They can be different in size
