The angle measures of quadrilateral rstu are shown. m∠r = (2x)° m∠s = (3x – 35)° m∠t = (x + 35)° the measure of angle u is unknown. can quadrilateral rstu be a parallelogram? a. yes, opposite angles r and t can be made equal to each other if x = 35. b. yes, consecutive angles r and s can be made equal to each other if x = 35. c. no, if x = 35, all three given angles measure 70°. the fourth angle would measure 150°. d. no, if x = 35, the three given angle measures make it impossible for the figure to be a quadrilateral. the correct answer is c. <

Which statements are true? if all angles of a quadrilateral are right angles, then the quadrilateral must be a square. two shapes are similar if and only if their corresponding angles are equal. all quadrilaterals have four sides, and the sum of all angles in a quadrilateral is 180°. if the diagonals of a quadrilateral are perpendicular bisectors, then the quadrilateral must be a rhombus. there are three vertices in a triangle, or there are four sides in a pentagon. any two triangles are either similar or congruent.
