Presentation Transcript
proving triangles are similar
Proving Triangles are Similar
  • AA ~ Thm: If two angles of one triangle are congruent to two angles in another triangle, then the triangles are similar.
slide3

SSS ~ Thm: If the 3 sides of one triangle are proportional to 3 sides of another triangle, then the triangles are ~.

slide4

SAS ~ Thm: If two sides of one triangle are proportional to two sides of another and the included angles are congruent, then the triangles are ~.

proofs
Proofs
  • These 3 Thms are used the same as the congruent triangles ones in proofs.
  • Properties of Similarity
example 2 verify that the triangles are similar
Example 2: Verify that the triangles are similar.
