Geometry

5. the (blank) of a trapezoid is the segment that connects the midpoints of the legs
6. (blank) is the distance around a circle
9. the locus or set of all points in a plane equidistant from a given point called the center
10. a segment with endpoints at the center and on the circle
11. a quadrilateral with exactly two pairs of consecutive congruent sides
18. non-adjacent exterior angles that lie on opposite sides of the transversal *3 words*
19. a segment with endpoints on the circle that passes through the center and is made up of 2 radii
20. (blank) is the shortest arc connecting two endpoints on a circle *2 words*
21. a line that intersects the circle in two spots

1. both pairs of opposite sides are parallel
2. (blank) is an arc with endpoints that lie on the diameter
3. interior angles that lie on the same side of a transversal *3 words*
4. an angle whose vertex is on the center *2 words*
7. planes that do not intersect *2 words*
8. if the object is below the level of the observer, then the angle between the horizontal and the observer's line of sight is called the (blank) *3 words*
12. angles that lie between 2 lines *2 words*
13. quadrilateral with exactly one pair of parallel sides
14. coplanar circles that have the same center *2 words*
15. lines that do not intersect and are not coplanar *2 words*
16. a line that touches a circle in one spot
17. a segment with endpoints on the circle
