2. angle whose measure is 180 degrees.
5. angle whose measure is greater than 90 degrees but less than 180 degrees.
6. a point that divides the segment into two congruent segments.
8. line, ray segment, or plane that divides a segment angle line etc. into two congruent parts.
10. angles that have the same measure.
11. triangle with all right angles
14. triangle with and obtuse angle
16. segments that have the same length.
18. triangle with no sides congruent
19. triangle with all sides congruent
20. a branch of mathematics that deals with points, lines, planes and solids and examines their properties.

1. triangle with at least two sides congruent
3. angle whose measure is 90 degrees.
4. has no size; length, width, or height. It is represented by a dot and named by a capital letter.
7. set of points which have infinite length but no width or height.
9. angle whose measure is between 0 degrees and 90 degrees.
12. triangle with a right angle
13. part of a line that consists of two points called endpoints and all points between them.
15. is the part of a line that contains an endpoint and all points extending in the other direction.
17. the figure formed by three segments joining three noncollinear points. Each of the three points is a vertex of the triangle and the segments are the sides.
