Across
- 2. Bisector
- 3. the point where the perpendicular drawn from the vertices to the opposite sides of the triangle intersect each other
- 7. a four-sided regular polygon which is also known as a quadrilateral with four equal sides
- 8. a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side.
- 10. a point which is at the same or equal distance from two given points
- 11. Bisector a line that bisects another line segment at a right angle, through the intersection point
- 12. a quadrilateral with reflection symmetry across a diagonal
- 13. a ray, segment, or line that divides a given angle into two angles of equal measures
- 15. a quadrilateral that has one pair of parallel sides
- 16. a quadrilateral with four right angles
- 17. a quadrilateral with four equal sides
- 18. made out of a straight line that's set at an angle instead of straight up or across
Down
- 1. a line that passes through two very specific points on a triangle: a vertex, or corner of a triangle, and its opposite side at a right, or 90-degree, angle
- 4. the point where all three perpendicular bisectors of a triangle meet
- 5. a quadrilateral with two pairs of parallel sides
- 6. the point where three bisectors of the interior angles of a triangle intersect and it is the center of the inscribed circle
- 9. all three sides have the same length, and all three angles are equal.
- 10. equal angles
- 14. the point in which the three medians of the triangle intersect
