- 3. Congruence Postulate, 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.
- 4. side opposite the right angle in a right triangle.
- 5. triangle, a triangle in which one angle measures exactly 90 degrees
- 7. Congruence Postulate, If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent.
- 12. angles, angles on the same side of a transversal and they must be equal
- 14. lines, two lines that even when extended infinitely will never intersect
- 15. Congruence Postulate, If two angles and the included side of one triangle are congruent to two angles and the included side of a second triangle, then the two triangles are congruent.
- 16. function, a function obtained by expressing the dependent variable of one function as the independent variable of another; f and g are inverse functions if f(x)=y and g(y)=x
- 18. Congruence Theorem, If two angles and a non-included side of one triangle are congruent to two angles and the corresponding non-included side of a second triangle, then the two triangles are congruent
- 19. angle, an angle with a measure of exactly 90 degrees
- 20. Theorem, In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
Down
- 1. Triangle, A triangle with at least two congruent sides.
- 2. lines, a pair of lines that meet to form a 90 degree angle)
- 6. the space between two lines or planes that intersect
- 8. Triangles, Two triangles are similar if they have the same shape but not necessarily the same size. The corresponding angles are equal, and the corresponding sides are proportional.
- 9. Triangles, Two triangles are congruent if they have exactly the same size and shape.
- 10. side of a right triangle that is not the hypotenuse.
- 11. angles, a pair of angles that add up to 180 degrees
- 13. Ratios, Ratios that relate two side lengths based on the reference angle
- 17. Triangle, A triangle with no congruent sides
