 Q5. Learn Cbse Class 8 Maths Mcq ABCD is a rectangle. Its diagonals meet at O. OA = 2x – 1, OD = 3x – 2. Find x A. 1 B. 2 C. 3 D. -1.
Ans: 1
Hint:
3x – 2 = 2x – 1 ⇒ x = 1.
 Q6. Mcq Class 8 Maths Chapter 3 Find the perimeter of the rectangle ABCD. A. 6 cm B. 12 cm C. 3 cm D. 24 cm
Ans: 12 cm
Hint:
Perimeter = 2 (4 + 2) cm = 12 cm.
 Q7. Mcq for Class 8 Maths Chapter 3 The four angles of a quadrilateral are in the ratio 1 : 2 : 3 : 4. The measure of its smallest angle is A. 120° B. 36° C. 18° D. 10°.
Ans: 36°
Hint:
Sum of the ratios = 1 + 2 + 3 + 4 = 10
∴ Smallest angle = $$\frac{1}{10}$$ × 360° = 36°
 Q8. Mcq Questions for Class 8 Maths with answers pdf Chapter 3 In a parallelogram ∠A : ∠B = 1 : 2. Then, ∠A = A. 30° B. 60° C. 45° D. 90°.
Ans: 60°
Hint:
∠A + ∠B = 180°
∠A : ∠B = 1 : 2
Stun of the ratios = 1 + 2 = 3
∴ ∠A = $$\frac{1}{3}$$ × 180° = 60°.
