Understanding Quadrilaterals | Class 8 Maths | NCERT Solutions

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.
