- 5. A segment the cuts an angle of a triangle in half
- 6. Lines that intersect at a right angle
- 7. The center of a triangle where the three perpendicular bisectors intersect. This is where the center of a circumscribed circle would be.
Down
- 1. A quadrilateral with two pairs of parallel sides
- 2. Lines that do not intersect
- 3. The center of a triangle where the three angle bisectors intersect. This is where the center of an inscribed circle would be.
- 4. A segment from a vertex of a triangle to the midpoint of the opposite side
- 5. A segment from a vertex of a triangle that is perpendicular to the opposite side
