Properties of Parallelograms 1) its opposite sides are congruent 2) its opposite are congruent If a quadrilateral is a parallelogram, then AND find the values of x and y. Using the parallelogram below, yo x + 4 12 65o x = y = find the values of x and y. Using the parallelogram, x = y = 2yo 2x + 3 15 60o If a quadrilateral is a parallelogram, then its consecutive angles are ____________________. complementary supplementary congruent also alternate interior angles In the parallelogram, the m ∡ KJM = 110o. Find the measure of ∡ KML K J m ∡ KML = 30o L o M If a quadrilateral is a parallelogram, then its _____________ bisect each other. sides consecutive angles opposite angles diagonals Q In the parallelogram below, find the values of x and y. x = y = P y + 1 5 M x - 1 R S PR = 4 Using the parallelogram, find the values ofm and n. m = n = 2n 16 9 - n 4m What is the measue of Angle 1? Find the value of a 1 Is BD = AC always? yes or no x = DE = BE = AC = BD = 14 AB = 11 In parallelogram ABCD, which angle is congruent to Angle ABC? <CDA <BCD <DAB <ABD |
