Question 1
1 / -0

In a quadrilateral ABCD, ∠A + ∠C = 225^oand ∠B = 75^o. What is the value of ∠D?

A
60^o

B
70^o

C
75^o

D
50^o

Solution

In the given quadrilateral ABCD,
∠A + ∠B + ∠C + ∠D = 360° [By angle sum property of a quadrilateral]
Rearranging angles, we get
(∠A + ∠C) + ∠B + ∠D = 360°
225° + 75° + ∠D = 360°
∠D = 360° - 225° - 75°
= 360° - 300°
= 60°
Question 2
1 / -0

Which of the following statements is/are correct?

A
Diagonals of a rectangle bisect each othe

B
In a rectangle, each angle is equal to 90^o.

C
In a rectangle, all the sides are equal.

D
Both (2) and (3)

Solution

Each angle of a rectangle is equal to 90^o.
Question 3
1 / -0

In a quadrilateral PQRS, ∠"P = 90o, ∠"Q = 110o and ∠"R = ∠"S. What is the value of ∠"R?

A
90°

B
85°

C
80°

D
70°

Solution

∠P = 90^o and ∠Q = 110^o
And ∠R = ∠S

Also, ∠P + ∠Q + ∠R + ∠S = 360^o [Sum of angles of a quadrilateral is 360^o.]

90° + 110° + ∠R + ∠R = 360° [∵∠R = S]
⇒ 200° + 2∠R = 360°

2∠R = 360° – 200°
2∠R = 160°

∠R = 80°
Question 4
1 / -0

Which of the following statements is not true?

A
A rectangle is a parallelogram.

B
A kite is not a parallelogram.

C
A rhombus is a square.

D
A trapezium is not a parallelogram.

Solution

A rhombus is not a square as all the angles of a square are equal to 90°, but all the angles of a rhombus are not necessarily equal to 90°.
