Answer explanation

If the sum of angles of a triangle is X and

the sum of the angles of a quadrilateral is Y,

then

• X = 2Y

• 2X = Y

• X = Y

• X +Y = 360°

Answer explanation

In the figure, ABCD is a

quadrilateral whose sides AB,

BC, CD and DA are produced

in order to P, Q, R and S. Then

x + y + z + t is equal to

Answer explanation

• 120⁰

• 130⁰

• 125⁰

• 115⁰

Answer explanation

In the given figure, if OA = 13 cm, AB = 24 cm

and OD ⊥ AB, then CD is equal to

• 3 cm

• 4 cm

• 8 cm

• 5 cm

Answer explanation

In the given figure, O is the centre of the

circle. If ∠ACB = 50°, then ∠AOB is equal to

• 60⁰

• 100⁰

• 90⁰

• 100⁰

Answer explanation

In the given figure, BC passes through the

centre of a circle where points A, B and C from a triangle and ∠B is 44° more than ∠C. The values

of x and y respectively are

• x = 4; y = 3

• x = 3; y = 5

• x = 7; y = 2

• x = 5; y = 2

Answer explanation

Assertion : In the given figure, ∠ABC = 70°

and ∠ACB = 30°. Then, ∠BDC = 80°.

Reason : Angles in the same segment of a circle

are equal.

• Assertion and Reason both are correct statements and Reason is the correct explanation of Assertion.

• Assertion and Reason both are correct statements but Reason is not the correct explanation of Assertion.

• Assertion is correct statement but Reason is wrong statement.

• Assertion is wrong statement but Reason is correct statement.
