Geometry

4. a special kind of point that describes the corners or intersections of geometric shapes
8. pairs of angles that add up to 180 degrees
10. two figures or objects that have the same shape and size
11. 2 parallel lines
12. Quadrilateral w/ 4 equal sides
14. two straight lines that never touch
15. quadrilateral w/ only 1 pair of parallel lines
16. If two pairs of sides of two triangles are equal in length, and the included angles are equal
18. a midline of a triangle creates a segment that is parallel to the base and half as long.

1. If three pairs of sides of two triangles are equal in length, then the triangles are congruent
2. a line segment connecting two non-adjacent vertices of a polygon
3. two congruent angles, both lying on the same side of the transversal
5. parallel sides are equal
6. relationship between two geometric objects that meet at a right angle
7. a transversal is a line that passes through two lines in the same plane at different points
9. 4 sided polygon
13. A quadrilateral with two distinct pairs of equal adjacent sides
17. a quadrilateral in which each diagonal bisects two opposite interior angles
19. a set of objects if the distances between that point and each object in the set are equal
20. the segment connecting the vertex of an angle in a triangle to the midpoint of the side opposite it
