$\begin{array}{cc}\text{Column - I}& \text{Column - II}\\ \text{A) Sum of all the angles}& \text{P) Right angles}\\ \text{of a quadrilateral is}& \\ \text{B) In a}\parallel \text{gm, the angle}& \text{Q) Rectangle}\\ \text{bisectors of two adjacent}& \\ \text{angles intersect at}& \\ \text{C) Angle bisectors of}& \text{R)}{45}^{\circ }\\ \text{a}\parallel \text{gm form a}& \\ \text{D) The diagonals of a}& \text{S) 4 right angles}\\ \text{square are equal and}& \\ \text{bisect each other at}& \\ \text{an angle of}& \end{array}$

Choose the correct option:

• A. $\left(A\right)\to s;\left(B\right)\to p;\left(C\right)\to q;\left(D\right)\to r$
• B. $\left(A\right)\to r;\left(B\right)\to p;\left(C\right)\to q;\left(D\right)\to s$
• C. $\left(A\right)\to p;\left(B\right)\to s;\left(C\right)\to q;\left(D\right)\to r$
• D. $\left(A\right)\to s;\left(B\right)\to p;\left(C\right)\to r;\left(D\right)\to q$

Answer 1

The correct option is A

$\left(A\right)\to s;\left(B\right)\to p;\left(C\right)\to q;\left(D\right)\to r$

(A) Sum of all the angles of a quadrilateral is 360° and 360° = 4 ×90°.
So the sum of all the angles of a quadrilateral is 4 right angles.
(B) In a||gm, the angle bisectors of two adjacent angles intersect at right angles.

(C) Angle bisectors of a $\parallel gm$ form a rectangle.
(D) The diagonals of a square are equal and bisect each other at an angle of ${45}^{\circ }$.
