Similar Triangles and Indirect Measurement

Similar Triangles and Indirect Measurement

Angle- Angle Similarity

• If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar

• 
   $if\ <A\ \cong\ <F\ and\ <B\ \cong<G,\ then\ \Delta ABC\ \sim\Delta FGH$  

Determine whether the triangles are similar. If so write a similarity statement

• Yes <A and <E have the same measurement

• If you find what the missing angle measurements are you notice these are similar Triangles.
