b) 1-a, b; 2-c, d
c) 1-a, b, c; 2-d
d) 1-a; 2-b, c, d
View Answer
Explanation: When two angles of a quadrilateral have a common side as an arm, they are called adjacent angles and the non-adjacent angles of a quadrilateral are opposite angles.
4. Match the following:

c) 1-a, b; 2-c, d
d) 1-a, d; 2-b, c
View Answer
Explanation: Two sides of a quadrilateral having a common end point are called adjacent sides of the quadrilateral. Two sides of a quadrilateral which are not having a common end point are called opposite sides of the quadrilateral.
5. Match the pairs:
A B 1. Adjacent sides a. ∠D, ∠B 2. Opposite Angle b. AB, DA 3. Opposite Side c. ∠D, ∠C 4. Adjacent Angle d. AB, DC
a) 1-c, 2-a, 3-d, 4-b
b) 1-b, 2-c, 3-d, 4-a
c) 1-b, 2-a, 3-d, 4-c
d) 1-c, 2-a, 3-d, 4-b
View Answer
Explanation: Two sides of a quadrilateral having a common end point are called adjacent sides of the quadrilateral. Two sides of a quadrilateral which are not having a common end point are called opposite sides of the quadrilateral. Two angles of a quadrilateral which have a common side as an arm are called adjacent angles. Two angles of a quadrilateral which are not adjacent angles are opposite angles.
6. Which are the interior and exterior points of the quadrilateral?
a) Interior point: L, Exterior point: M
b) Interior Point: P, Exterior point: O
c) Interior point: O, Exterior point: K
d) Interior point: L, Exterior point: O
View Answer
Explanation: Points inside the quadrilateral are called interior points of the quadrilateral. Points outside the quadrilateral are called the exterior points of the quadrilateral.
7. Find ∠B using the information given in the figure.
a) 10°
b) 100°
c) 110°
d) 50°
View Answer
Explanation: By Angle sum property of Quadrilateral,
∠A + ∠B + ∠C + ∠D = 360°
⇒ 110° + ∠B + 120° + 30° = 360°
⇒ ∠B = 100°.
8. If ∠P + ∠Q = 240 and ∠R = 90, find the remaining angle of the quadrilateral PQRS.
a) 30°
b) 40°
c) 50°
d) 60°
View Answer
Explanation: By Angle sum property of Quadrilateral,
∠P + ∠Q + ∠R + ∠S = 360°
240° + 90° + ∠S = 360°
⇒ ∠S = 30°.
9. Find the value of ∠O from the given figure.
a) 110°
b) 30°
c) 90°
d) 100°
View Answer
Explanation: Sum of interior angles of a pentagon is 540°
⇒ ∠K + ∠L + ∠M + ∠N + ∠O = 540°
⇒ ∠O = 540° – 440°
⇒ ∠O = 100°.
10. Find the remaining angle of the given figure.
a) 260°
b) 270°
c) 300°
d) 290°
View Answer
Explanation: Sum of interior angles of a hexagon is 720°
⇒ ∠A + ∠B + ∠C + ∠D + ∠E + ∠F = 720°
⇒ ∠F = 720° – 43°
⇒ ∠F = 290°.
