Similarity Flashcards
If two of the angles of one triangle are congruent
to two angles of another triangle, the two triangles are similar.
AA
If the corresponding sides of two triangles are
proportional, then the two triangles are similar.
SSS
If an angle of one triangle is congruent to an
angle in another triangle and the sides that include the angle are proportional, the two triangles
are similar.
SAS
If a line segment within a triangle is parallel to one side and intersects the other two sides, then it divides those two sides proportionally.
Side-Splitter Theorem
The angle bisector of an angle in a triangle divides the opposite side into two segments that are proportional to the other two sides of the triangle.
