Quick Q&A Before You Revise
How do I know whether to use similarity or congruence?
Use congruence when both shape and size are exactly the same. Use similarity when the shapes match but one figure can be a scaled version of the other.
What is the biggest caution in area questions of similar triangles?
Do not use the side ratio directly for area. Always square the side ratio first.
