TRIANGLE PROOFS

5. leg the side directly across from the right angle.
7. angles that are in the same position. made by a line cutting through two or more other lines.
8. above the ground or above the sea level
9. having all sides or faces equal an equilateral triangle
11. mean is a special type of average where we multiply the numbers together and then take a square root
14. Anything equals itself; x=x
16. Any two angles that have a sum of 180 degrees
18. Lines Lines that intersect to form right angles or 90 degrees
20. congruency If two angles and the non-included side of one triangle are congruent to two angles and the non - induced side of another triangle, then the triangles are congruent

1. The Ray that divides an angle into two congruent angles
2. is a side of a polygon or a face of a polyhedron
3. A corner of a figure
4. Having the exact same size and shape and there by having the exact same measures
6. congruency If 3 sides of 1 triangle of one congruent to 3 sidesof another triangle
10. a triangle having two sides of equal length.
12. Two lines that do not intersect and are always the same distance apart.
13. The point that divides a segment into two congruent segments
15. congruency If two sides and the Included angle of one triangle are Congruent to two sides
17. Corresponding Parts of Congruent Triangles are congruent by definition of congruence
19. congruency two angles and the Included side of One triangle are congruent to two angles and the 1 included Side of another triangle, then the triangles are congruent
