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°. 
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°. 
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. 
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°. 
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°. 
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. 
Hint:
Number of sides = \(\frac{360°}{24°}\) = 15.
Q7.  Class 8 Maths Mcq Chapter 3 How many sides does aregular polygon have if each of its interior angles is 165° ? 
A. 12 

B. 24 

C. 9 

D. 6. 
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. (\(\frac{2n4}{n}\)) 90° 

C. n 90° 

D. 2n right angles. 
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°. 
Hint:
n = 5, (n – 2) 180° = (5 – 2) 180° = 540°
Fifth angle
= 540° – (40° + 75° + 125° + 135°)
= 540° – 375° = 165°
