3. a line segment joining two points
4. a quadrilateral with two pairs of adjacent sides equal
8. triangle a triangle containing a 90 degree angle
10. the point of intersection of the three right bisectors of the sides of a triangle
12. a triangle having sides unequal in length.
13. the point that divides a line segment into two equal segments
14. a quadrilateral with one pair of parallel sides.
16. a triangle with exactly two equal sides
17. a line segment that joins a vertex of a triangle to the midpoint of the opposite side
18. the point at which the three angle bisectors of a triangle meet
19. lying on the same line
21. triangle a triangle with all three sides equal
22. a quadrilateral with two pairs of opposite sides that are parallel

1. meeting at a single point.
2. The point where three medians of a triangle intersect.
5. the point at which the three altitudes of a triangle meet
6. a two-dimensional closed shape with 4 equal sides and 4 vertices.
