Across
- 4. Angles which are inside the parallel lines and on opposite sides of the transversal. They are congruent.
- 10. Angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, these angles are congruent.
- 12. If a ray bisects an angle of a triangle, then it divides the opposite side of the triangle into segments that are proportional to the other two sides.
- 14. A line that crosses at least two other lines.
- 15. A triangle with two congruent sides and two congruent base angles
Down
- 1. A triangle with three equal sides and three equal angle.
- 2. The pair of angles on one side of the transversal but inside the two parallel lines. These angles are supplementary.
- 3. The three interior angles of a triangle will always have a sum of 180 degrees
- 5. The angle that is ALWAYS across from the longest side in a triangle
- 6. The exterior angle of a triangle is equal to the sum of the two remote interior angles.
- 7. Angles which are outside the parallel lines and on opposite sides of the transversal. They are congruent.
- 8. A triangle with no congruent sides or angles
- 9. The angles that do not share a vertex of a triangle with the exterior angle.
- 11. The angles opposite each other when two lines intersect. They are always congruent.
- 13. The angles that are opposite the congruent legs of an isosceles triangle.
