 The mirro image produced by flipping a figure over a line is called a _____________________. reflection __________________ angles have measures equal to 180 degrees. straight Any polygon with four sides and four angles is a ___________________________. quadrilateral _______________ angles are two angles that have the same vertex, share a common side, and do not overlap. vertical A line that intersects two or more other lines is call a _____________________. transversal A figure has a ___________________________ if it can be folded over a line so that one half matches the other half. line of symmetry A ______________________ is the movement of a figure from one position to another without turning it. translation A parallelogram with four congruent sides is called a _____________________. rhombus An ______________ triangle has three acute angles. acute The sum of the measures of ______________________ angles is 90 degrees. complementary _______________________ are angles in the same position on two parallel lines that are cut by a transversal. corresponding angles ____________________ is a property where a figure is rotated less than 360 degrees about its center so that it looks exactly like the original figure. rotational symmetry _________________ are angles on opposite sides of the transversal and inside the other two lines which are congruent. alternate interior angles ________________ are angles on opposite sides of the transversal and outside the other two lines which are congruent. alternate exterior angles A __________________ is a quadrilateral with one pair of parallel opposite sides. trapezoid
