Geometry

Across
1. 3. any angle greater than 90°
2. 8. two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
3. 9. The point at which at which the three perpendicular bisectors intersect in a triangle
4. 11. the side of the triangle that is opposite the right angle
5. 13. The point at which the three angle bisectors intersect in a triangle
6. 16. angles that have equal measure.
7. 17. a triangle in which all three sides have different lengths
8. 18. the three sides of a triangle are congruent to the three sides of another triangle
9. 19. the sum of the measures of the angles of a triangle is 180°
Down
1. 1. is used to find a missing side length on a right triangle (a^2 + b^2 = c^2)
2. 2. an angle of exactly 90°
3. 4. corresponding parts of congruent triangles are congruent
4. 5. a segment that joins the midpoint of two sides of a triangle
5. 6. the exact middle point of a line
6. 7. a triangle that has two sides of equal length
7. 10. a triangle in which all three sides have the same length
8. 12. the two sides of a right triangle that make up the 90 degree angle
9. 14. two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
10. 15. angles that measure less than 90°.
11. 18. two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
12. 20. the corresponding lengths of their hypotenuse and one leg are equal.
