12When the third angle on an isosceles triangle is a right angle, it is called a ____________________Right Isosceles Triangle
13A line segment joining a vertex to the midpoint of the opposite side. A triangle has three of these.Median
14The point where the three medians of the triangle intersect. "The center of gravity" of the triangle.Centroid
15A line segment joining the midpoints of two sides of a triangle. A triangle has three of these.Midsegment
16A midsegment is parallel to the third side and _______ its length.half
17The segment joining the centroid and the midpoint is __________ of the length of the median.one-third
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.
24AASIf two triangles and a NON-INCLUDED side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
