Match the following
two triangles are considered similar if at least two corresponding angles are congruent
AA Similarity Postulate
two triangles are similar if all their corresponding angles are congruent and their corresponding sides are proportional
SSS Similarity Theorem
If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar.
SAS Similarity Theorem
in any triangle, if a line intersects two sides of the triangle and is parallel to the third, then the intersecting line divides the sides proportionally
Triangle Proportionality Theorem
an angle bisector of an angle of a triangle divides the opposite side into two parts that are proportional to the other two sides of the triangle
Angle Bisector Theorem
State if the pair triangles are similar. If they are similar, state how you know the triangles are similar.
