a/b=c/d : ad=cb
ad=bc a/c=b/d
Two Polygons are similar if their vertices can be paired so that: (1) Corresponding angles are congruent. (2) Corresponding sides are in proportions. (Their lengths have the same ratio.)
AA Similarity Postulate If two angles of one triangle are congruent to two angles of another triangle then the triangles are similar
SAS Similarity If an angle of one triangle is congruent to an angle of another triangle and the sides including those angles are in proportion, then the triangles are similar
SSS Similarity If the sides of two triangles are in proportion, then the triangles are similar
Triangle Proportionally Theorem If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.
If three parallel lines intersect two transversals, then: they divide the transversals proportionally
Triangle Angle-Bisector Theorem If a ray bisects an angle of a triangle, the it divides the opposite side into segments proportional to the other side.
Geometric Mean x=(square root)(a)(b)
If the altitude is drawn to the hypotenuse of a right triangle, then: the two triangles formed are similar to the original triangle and to each other.
