Across
- 1. angles – angles that have the same measure.
- 7. a vertex of the triangle and the segments are the sides.
- 10. the part of a line that contains an endpoint and all points extending in the other direction.
- 11. angle – angle whose measure is between 0 degrees and 90 degrees.
- 13. bisector – ray that divides an angle into two congruent adjacent angles.
- 14. points – points that do not lie on the same line.
- 17. points – points that lie on the same plane.
- 19. angle – angle whose measure is 90 degrees.
- 20. angle – angle whose measure is greater than 90 degrees but less than 180 degrees.
- 22. triangle – triangle with a right angle.
- 23. part of a line that consists of two points called endpoints and all points between them.
Down
- 2. points – points that do not lie on the same plane.
- 3. – set of points which has infinite length but no width or height. A line is named by a lower case letter
- 4. of a segment – line, ray segment, or plane that divides a segment into two congruent segments. Midpoint of a segment – a point that divides the segment into two congruent segments.
- 5. – set of points that has infinite length and width but no height. We name a plane with a capital
- 6. font’ letter.
- 8. – the figure formed by three segments joining three noncollinear points. Each of the three points
- 9. - has no size; length, width, or height. It is represented by a dot and named by a capital letter.
- 12. points – points that lie on the same line.
- 15. triangle- triangle that has all acute angles.
- 16. segments – segments that have the same length.
- 18. any two points on the line.
- 21. angle – angle whose measure is 180 degrees.
