Similar Triangles - A pair of triangles that have equal corresponding angles and proportional corresponding sides.
Equiangular Triangles:
A pair of triangles that have corresponding angles equal.
The ratio of any two corresponding sides in two equiangular triangles is always the same.
Criteria for Triangle Similarity:
Angle-Angle-Angle (AAA) Similarity
Side-Angle-Side (SAS) Similarity
Side-Side-Side (SSS) Similarity
Basic Proportionality Theorem:
When a line is drawn parallel to one side of a triangle to intersect the other sides in distinct points, the other two sides are divided in the same ratio.
Converse of Basic Proportionality Theorem:
In a pair of triangles when the corresponding angles are equal, their corresponding sides are proportional and the triangles are similar.
