 Q1. Ncert Class 8 Maths Mcq Questions Two adjacent angles of a quadrilateral measure 130° and 40°. The sum of the remaining two angles is A. 190° B. 180° C. 360° D. 90°.
Ans: 190°
Hint:
Sum = 360° – (130° + 40°) = 190°.
 Q2. CBSE Class 8 Maths Chapter 3 Mcq The measures of two angles of a quadrilateral are 110° and 100″. The remaining two angles are equal. The measure of each of the remaining two angles is A. 30° B. 60° C. 75° D. 45°.
Ans: 75°
Hint:
Required measure
= $$\frac{360°-(110°+100°)}{2}$$ = 75°
 Q3. CBSE Class 8 Maths Chapter 3 Mcq Questions The number of sides of a regular polygon, whose each exterior angle has a measure of 45°, is A. 4 B. 6 C. 8 D. 10.
Ans: 8
Hint:
Number of sides = $$\frac{360°}{45°}$$ = 8.
 Q4. CBSE Class 8 Maths Understanding Quadrilaterals Mcq The measure of each exterior angle of a regular polygon of 9 sides is A. 30° B. 40° C. 60° D. 45°.
Ans: 40°
Hint:
Required measure = $$\frac{360°}{9}$$ = 40°.
 Q5. CBSE Class 8 Maths Mcq Questions The measure of each exterior angle of a regular polygon of 15 sides is A. 30° B. 45° C. 60° D. 24°.
Ans: 24°.
Hint:
Required measure = $$\frac{360°}{15}$$ = 24°.
 Q6. CBSE Class 8 Maths Understanding Quadrilaterals Mcq Questions How many sides does a regular polygon have if the measure of an exterior angle is 24° ? A. 6 B. 9 C. 15 D. 12.
Ans: 15
Hint:
Number of sides = $$\frac{360°}{24°}$$ = 15.
 Q7. Class 8 Maths Mcq Chapter 3 How many sides does a-regular polygon have if each of its interior angles is 165° ? A. 12 B. 24 C. 9 D. 6.
Ans: 24
Hint:
Exterior angle = 180° – 165° = 15°
∴ Number of sides = $$\frac{360°}{15°}$$ = 24.
 Q8. Class 8 Maths Mcq online test In a regular polygon of n sides, the measure of each internal angle is A. $$\frac{360°}{n}$$ B. ($$\frac{2n-4}{n}$$) 90° C. n 90° D. 2n right angles.
Ans: ($$\frac{2n-4}{n}$$) 90°
 Q9. Class 8 Maths Mcq with answers The four angles of a pentagon are 40°, 75°, 125° and 135°. The measure of the fifth angle is A. 165° B. 170° C. 160° D. 175°.
Ans: 165°
Hint:
n = 5, (n – 2) 180° = (5 – 2) 180° = 540°
Fifth angle
= 540° – (40° + 75° + 125° + 135°)
= 540° – 375° = 165°
 Q10. Learn Cbse Class 8 Maths Mcq The sum of the internal angles of a polygon is 10 right angles. Then the number of sides is A. 5 B. 6 C. 7 D. 8.
Ans: 7
Hint:
(n – 2) 180° = 10 x 90°
⇒ n = 7.
