How to tell if two triangles are congruent?
Understand the Problem
The question is asking for the criteria or methods to determine whether two triangles are congruent. This involves understanding specific properties and rules in geometry that relate to triangle sides and angles.
Answer
Two triangles are congruent if their corresponding sides and angles match following SSS, SAS, ASA, AAS, or HL criteria.
The final answer is that two triangles are congruent if their corresponding sides and angles are equal based on criteria like SSS, SAS, ASA, AAS, or HL.
Answer for screen readers
The final answer is that two triangles are congruent if their corresponding sides and angles are equal based on criteria like SSS, SAS, ASA, AAS, or HL.
More Information
Congruence means the triangles can be perfectly overlapped, revealing they are identical in shape and size. The criteria SSS, SAS, ASA, AAS, and HL are standard methods to prove this.
Tips
A common mistake is to assume triangles with similar shapes are congruent without verifying the exact length of their sides and angles.
