Across
- 2. Angles formed on the 'outside' of two parallel lines cut by a transversal, or by extending one side of a triangle
- 3. Pair of angles that measure 180 degrees
- 6. A pair of angles whose sum is 90 degrees
- 8. Angle that measures less than 90 degrees
- 9. type of angle that share a common side and vertex
- 10. none of the sides are congruent
- 11. Type of triangle with two congruent side length
- 13. Pair of angles that are formed by intersecting lines across the vertex from one another
- 14. Pair of straight lines that form four right angles at the intersection
Down
- 1. Angles that are in the same relative position formed when two parallel lines are intersected by a transversal line
- 4. Straight lines that never intersect, when graphed they have the same slope but different intercepts
- 5. One that measures 90 degrees
- 7. Triangle with all acute angles
- 12. Angle that measures more than 90 degrees
