Three angles of a quadrilateral are 45°, 90° and 120°. Find its perimeter.įind the sum of all internal angles of a regular pentagon. Lengths of the two adjacent sides of a parallelogram are 12 cm and 8 cm. Find the measure of each angle of the parallelogram. The measure of two adjacent angles of a parallelogram is in the ratio of 7 : 3. Practice Problems Based on the Chapter Quadrilaterals Class 9 But before going to your textbook questions, let us solve these problems to evaluate your understanding of Quadrilaterals. Using these problems, you can solve your textbook problems easily. So, you have solved all types of problems related to quadrilaterals. (iv) diagonals are perpendicular to each other (iv) diagonals are perpendicular to each Other (vii) one of the diagonal bisects the other Choose the quadrilaterals with their properties Find x and yĪns: Since in Parallelogram ABCD opposite sides are parallel and equal In the following figure, given a parallelogram ABCD. Kite shape has equal adjacent sides and in rhombus all sides are equal which means adjacent sides will also be equal. Sum of interior angles= $5 - 2 \times 180 = 540$ Find the sum of all internal angle of a pentagon that is regular.Īns: Sum of interior angles of a n sided polygon is $n - 2 \times 180$ The number of Diagonals in triangle is _Īns: Sum of all internal angles of quadrilateral = 360 A parallelogram with one angle 90° is _ħ.
