4. two straight lines that never touch
6. 2 parallel lines
7. 4 sided polygon
8. pairs of angles that add up to 180 degrees
9. a segment connecting two consecutive midpoints of a triangle
10. An angle bisector is a ray that cuts the angle exactly in half, making two equal angles
12. a set of objects if the distances between that point and each object in the set are equal
15. a quadrilateral in which each diagonal bisects two opposite interior angles
16. a special kind of point that describes the corners or intersections of geometric shapes
17. Quadrilateral w/ 4 equal sides
18. A quadrilateral with two distinct pairs of equal adjacent sides
19. parallel sides are equal

1. the segment connecting the vertex of an angle in a triangle to the midpoint of the side opposite it
