Geometry Terms

4. – points that do not lie on the same line.
7. - is the part of a line that contains an endpoint and all points extending in the other direction.
10. – has no size; length, width, or height. It is represented by a dot and named by a capital letter.
11. – angle whose measure is 180 degrees.
12. – ray that divides an angle into two congruent adjacent angles.
15. – points that lie on the same line.
16. – set of all points.
18. – 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.
20. – set of points which has infinite length but no width or height. A line is named by a lower case letter or by any two points on the line.

1. – a point that divides the segment into two congruent segments.
2. – angles that have the same measure.
3. – set of points that has infinite length and width but no height. We name a plane with a capital letter.
5. – points that lie on the same plane.
6. – points that do not lie on the same plane.
8. – angle whose measure is between 0 degrees and 90 degrees.
9. – part of a line that consists of two points called endpoints and all points between them.
13. – line, ray segment, or plane that divides a segment into two congruent segments.
14. – angle whose measure is greater than 90 degrees but less than 180 degrees.
17. – angle whose measure is 90 degrees.
19. - triangle that has all acute angles.
