Across
- 2. the angles across from each other where two lines cross
- 3. if you add all three interior angles, they will add up to 180 degrees.
- 7. a triangle with two equal sides and angles.
- 13. angles The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
- 14. a pair of angles formed when a transversal line intersects two parallel lines, where the angles are located on the same side of the transversal and are both inside the parallel lines.
- 16. a point where two straight lines or rays meet.
- 17. a geometric figure is the same size and shape as itself; essentially, a figure is always equal to itself.
- 18. the angles formed at the "bottom" of the triangle and the base is considered as the bottom side.
- 19. two angles next to each other that together make a straight angle.
- 20. the longest side of a right triangle, which is always opposite of the right angle.
Down
- 1. a pair of angles formed when a transversal intersects two parallel lines, where both angles lie outside the parallel lines and on the same side of the transversal.
- 4. angles that will be in the exact same place as the other line if you pick one line up and place it on top of the other.
- 5. a triangle with all three sides and angles of equal length.
- 6. two angles that when added together equal 180 degrees.
- 8. states that when a triangle's side is extended, the exterior angle formed is equal to the sum of the measures of the two opposite interior angles of the triangle
- 9. a triangle where all three sides are of different lengths
- 10. a pair of angles that lie on the outside of two lines cut by a transversal, but on opposite sides of the transversal.
- 11. if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
- 12. two angles whose measures add up to 90 degrees.
- 15. a line that passes through two lines in the same plane
