Geometry

2. angle side, If two sides and the included angle of one triangle are congruent to two sides and the included angle of a second triangle then the two triangles are congruent
7. 90-degree angle
9. Sides, Sides that are the same length on the same two shapes
11. angle less than 90 degrees
12. Angle, the angle in between two sides
14. side side, When three sides of one triangle are congruent to three sides of a second triangle then the two triangles are congruent
16. In a right triangle the sides adjacent to the right angle
17. All three sides are congruent
