geometry
Across
- 2. a triangle that has three acute angles
- 3. if two angles are complements of the same angle or of congruent angles then the two angles are congruent
- 5. angles if two coplanar angles that have a common side and a common vertex but no common interior points
- 6. a triangle that has three congruent sides
- 8. a triangle that has one obtuse angle
- 10. if two lines are cut by a transversal so that alternate interior angles are congruent then the lines are parallel
- 14. is an angle formed by a side and an extension of an adjacent sides
- 15. a triangle that has no congruent sides
- 16. a triangle that has a least two sides congruent
- 17. if two lines are cut by a transversal so that same side interior angles are supplementary then the lines are parallel
- 18. if two sides and the included angle of one triangle are congruent to two sides and the included angle of anot
Down
- 1. are two angles whose sides form two pairs of opposite rays
- 2. if two parallel lines are cut by a transversal then the pairs of alternate interior angles are congruent
- 3. if two angles are supplements of the same angle or of congruent angles then two angles are congruent
- 4. triangle then the two triangles are congruent
- 7. if the three sides of one triangle are congruent to the three sides of another triangle then two triangles are congruent
- 9. if two parallel lines are cut by a transversal then the pairs of corresponding angles are congruent
- 10. if two lines are cut by a transversal so that corresponding angles are congruent then the lines are parallel
- 11. if two parallel lines are cut by a transversal then the pairs of interior angles on the same side of the transversal are supplementary
- 12. the sum of the measures of the angles of a triangle is 180
- 13. a triangle that has one right angle
