18When two triangles have corresponding angles that are congruent, the triangles are similar.AA (Angle-Angle) Similarity
19When two triangles have corresponding angles that are congruent and corresponding sides with identical ratios, the triangles are similar.SAS (Side-Angle-Side) Similarity
20The Pyhagorean Theroem can only be used with _______ triangles.right-angled
21SSSIf the three sides of the triangle are congruent to three sides of another triangle, the the triangles are congruent.
22SASIf two sides and the INCLUDED ANGLE of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent
23ASAIf two angles and the INCLUDED SIDE of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
