Quadrilaterals Class 8 Very Short Question Answer

Question 1.

Write the pairs of opposite sides of a quadrilateral ROPE.

Solution:

RO and PE; RE and OP.

Question 2.

If three angles of a quadrilateral are 120°, 50° and 130°, find its fourth angle.

Solution:

Fourth angle = 360°-(120°+50°+130°)

= 360° - 300° = 60°.

Question 3.

Write the diagonals of the rhombus RING.

Solution:

Diagonals are RN and IG.

Question 4.

If ∠A of a parallelogram ABCD is 50°, then find the angle B of the parallelogram.

Solution:

∠A + ∠B = 180°.

So, ∠B = 180° - ∠A

= 180° - 50°

= 130°.

Question 5.

If diagonal PR of a rectangle PQRS is 6 cm, then find the other diagonal QS of the rectangle.

Solution:

Diagonals of a rectangle are equal.

So, QS = PR = 6 cm.
