Here, PQ ‖ RT and PR ‖ QT. The opposite sides of a parallelogram are equal. Here, PQ = RT and PR = QT. The opposite angles of a parallelogram are equal. Here, ∠P = ∠T and ∠Q = ∠R.
WebDec 17, 2016 · Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles. (6x + 20)° + (4x + 10)° = 180°. 30° + 10x = 180°. 10x = 150°. x = 15°. m∠A = 6x + 20°. WebApr 6, 2024 · In a parallelogram, adjacent angles are supplementary. ⇒ a + b = 180º ................ (1) After bisecting the angles with measures, a and b we get the measures of the angles as a 2 a n d b 2 From equation 1 We have, ( a + b) 2 = 180 2 ⇒ a 2 + b 2 = 90º Now, the bisectors will form a triangle and sum of the angles of a triangle is 180º.
