Math Example

Understanding the concept of triangle similarity is crucial in geometry, often determined through relationships involving angles and sides. One method to establish similarity is the Angle-Angle (

Math Example

In △ABC and △A'B'C', if AB: A'B'=AC:A'C' and ∠A=∠A', then△ABC ~△A'B'C'

In △ABC and △A'B'C', if AB: A'B'=AC:A'C'=BC:B'C', then△ABC ~ △A'B'C'
