Geometry

1. triangle a triangle that has one of its interior angles equal to 90 degrees or any one angle is a right angle.
4. a polygon with 3 sides.
7. angles nonadjacent angles formed by intersecting lines.
9. a theorem that states that if two angles and the non-included side of one triangle are congruent to the corresponding two angles and side of a second triangle.
11. exactly equal in size and shape.
14. in the same location in two or more objects.
15. a postulate that states that if two angles and the included side of one triangle are congruent to the corresponding two angles and included side of a second triangle.
16. two rays that share a common endpoint, referred to as a vertex from an angle; the rays form the sides of the angle.
17. in a right triangle the sides opposite the acute angles.
18. a postulate that states that if three sides of one triangle are congruent to three sides of a second triangle.

2. a theorem that states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of a second triangle.
3. a pair of non-overlapping angles that have a common vertex and a common ray
5. a side between two angles or the angle between two sides.
6. line segment that joins two vertices in a shape.
8. statement two triangles are said to be congruent if one can be placed over the other so that they coincide.
10. in a right triangle, the side opposite the right angle.
12. a side or angle that isn't between two things.
13. a postulate that states that if two sides and the included angle of one triangle are congruent to the corresponding two sides and included angle of a second triangle.
