DESCRIPTION
BASIC GEOMETRY Section 7.3: Triangle Similarity: AA, SSS, & SAS. 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. - PowerPoint PPT PresentationTRANSCRIPT
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.
SSS ~ Thm: If the 3 sides of one triangle are proportional to 3 sides of another triangle, then the triangles are ~.
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 These 3 Thms are used the same as the
congruent triangles ones in proofs. Properties of Similarity
