- 10. is a straight line that extends from a point.
- 12. term is a term or word that doesn't require further explanation or description.
- 14. is a geometric figure made with only a straightedge and compass.
- 15. is a general conclusion proposed to be proved upon the basis of certain given hypotheses or assumptions; or, a general conclusion that has been proved.
- 16. pair are two angles that are adjacent (share a leg) and supplementary .
- 19. is the sum of all lengths of its its sides.
- 21. are two angles that add up to 180°.
- 25. rays are collinear rays with the same endpoint.
- 26. is a three dimensional figure that has a circular base, a vertex not in the plane of the circle, and a curved lateral surface.
- 28. angle is an angle that measures 90° or /2 radians. It is the angle between two perpendicular lines such as the corner of a square or two perpendicular planes such as the wall and the ground.
- 29. is a point B that lies on the line connecting two points A and C and has one of the two points on each side of it.
- 30. is when two lines lie on the same plane and never intersect.
- 32. angle is an angle whose measure is between 90 and 180.
- 33. is formed by two rays with the same endpoint.
- 35. means the same measure.
- 37. segment is a part of a line between two points called endpoints.
- 38. is a closed plane figure bounded by at least three line segments.
- 40. angles are two coplanar angles that have a common side and a common vertex but no common interior points.
- 41. is a unit of measure used to measure the magnitude of an angle, equal in magnitude to 1/360 of a complete revolution.
- 42. is a point at which the two rays of an angle meet or the intersection point of two sides of a plane figure.
Down
- 1. is a space figure with two parallel polygonal bases that are the same shape and the same size.
- 2. means on the same line.
- 3. is to be on the same plane.
