The angles of a quadrilateral are in the ratio 3:5:9:13. Find all the angles of the quadrilateral. Solution: Let the common ratio between the angles be = x. We know that the sum of the interior angles of the quadrilateral = 360° Now, 3x+5x+9x+13x = 360° ⇒ 30x = 360° ⇒ x = 12° Angles of the quadrilateral are: 3x = 3×12° = 36° 5x = 5×12° = 60° 9x = 9×12° = 108° 13x = 13×12° = 156° 2. If the diagonals of a parallelogram are equal, then show that it is a rectangle. Solution: Given that, AC = BD To show that ABCD is a rectangle if the diagonals of a parallelogram are equal. To show ABCD is a rectangle, we have to prove that one of its interior angles is right angled. Proof, In ΔABC and ΔBAD, AB = BA (Common) BC = AD (Opposite sides of a parallelogram are equal) AC = BD (Gi...
