**4.**4 sided polygon**5.**two straight lines that never touch**6.**a transversal is a line that passes through two lines in the same plane at different points**7.**parallel sides are equal**9.**If two pairs of sides of two triangles are equal in length, and the included angles are equal**12.**a special kind of point that describes the corners or intersections of geometric shapes**14.**2 parallel lines**16.**a midline of a triangle creates a segment that is parallel to the base and half as long.**17.**A quadrilateral with two distinct pairs of equal adjacent sides**18.**If three pairs of sides of two triangles are equal in length, then the triangles are congruent**20.**a set of objects if the distances between that point and each object in the set are equal
