##### Across

**4.**is a line segment joining two nonconsecutive vertices of a polygon or polyhedron. Informally, any sloping line is called diagonal.**5.**is a regular quadrilateral that has four equal sides and four equal angles**6.**are points where sides meet**7.**Angle are angles that occur one right after the other. Consecutive angles are on either end of the same line segment in a polygon.**10.**lines are lines that never meet**12.**Angles are two Angles when they add up to 180 degrees**13.**is a flat shape with 4 equal straight sides. It looks like a diamond. . All sides have equal length.**14.**Pairs are Adjacent supplementary angles**16.**Lines are lines that intersect at right angles to each other**22.**is a four sided shape that has two sides that are parallel and two sides that are not parallel**23.**are qual angles
