Properties of quadrilaterals: Sum of angles of a quadrilateral is equal to 360. Each of the angles is a right angle. 60° + n = 180° ⇒ n = 180° – 60° = 120° (Linear pair) The figure is having five sides and is a pentagon. Ans. One side of triangle = 180°- (90° + 30°) = 60°, b) Sum of all angles of quadrilateral = 360°, One side of quadrilateral = 360°- (60° + 80° + 120°) = 360° – 260° = 100°, x + y + z + w = 60° + 100° + 120° + 80° = 360°, 125° + m = 180° ⇒ m = 180° – 125° = 55° (Linear pair), 125° + n = 180° ⇒ n = 180° – 125° = 55° (Linear pair), x = m + n (exterior angle of a triangle is equal to the sum of 2 opposite interior 2 angles), Two interior angles are right angles = 90°, 70° + m = 180° ⇒ m = 180° – 70° = 110° (Linear pair). Given a parallelogram ABCD. NCERT Solutions and Exemplar problems both are important for class 8 Mathematics practice. In ΔABC, ∠1 + ∠2 + ∠3 = 180° (angle sum property of triangle), ∠4 + ∠5 + ∠6 = 180° (angle sum property of triangle), ∴, ∠1 + ∠2 + ∠3 + ∠4 + ∠5 + ∠6 = 180° + 180°. Sum of measures of all angles is 360°. (i) AD = BC (Opposite sides of a parallelogram are equal), (ii) ∠DCB = ∠DAB (Opposite angles of a parallelogram are equal) (iii) OC = OA (Diagonals of a parallelogram are equal), 2.
