**Question 1.** Draw a rough sketch of a quadrilateral PQRS. Draw its diagonals. Name them. Is the meeting point of the diagonals in the interior or exterior of the quadrilateral?

**Answer 1 :**

Diagonal : PR and QS

Diagonal meet at point O which is in the interior of quadrilateral PQRS.

**Question 2.** Draw a rough sketch of a quadrilateral KLMN. State,

(a) two pairs of opposite sides,

(b) two pairs of opposite angles,

(c) two pairs of adjacent sides

(d) two pairs of adjacent angles.

**Answer 2 : **

(a) Pair of opposite sides : KL and MN, KN and LM

(b) Pair of opposite angles : ∠K and∠M,∠L and∠N

(c) Pair of adjacent sides : KN and NM, KL and LM

(d) Pair of adjacent angles :∠K and∠N,∠L and∠M
