Two rays with a common starting point make ______________

Option 3 is correct because according to definition two rays with a common initial point make an angle

Identify the angles in the given figure.

Option 2 is correct because the name of an angle must have vertex as a middle letter. Option 1 is wrong because there is no clarity about the naming of angle Option 3 is wrong because all the angles mentioned in option does not have vertex as middle letter Option 4 is wrong because all the angles mentioned in option does not have vertex as middle letter

How many interior angles are present in the given figure?

Option 3 is correct because the given figure has 14 angles i.e ∠A,∠B,∠C,∠D,∠E,∠F,∠G,∠H,∠I,∠J,∠K,∠L,∠M,∠N

How many angles are present in the given figure?

Option 3 is correct because the given figure has 6 angles i.e ∠AOB, ∠BOC, ∠COD, ∠AOC, ∠BOD, ∠AOD

Which point lies in the interior of ∠PQR?

Option 3 is correct because the region in the internal part of an angle is called its interior. Here, the point M lies in the interior of ∠PQR. Option 1 is incorrect because point S lies in the exterior of ∠PQR. Option 2 is also incorrect because point Q is the vertex i.e it is on the boundary of ∠PQR. Option 4 is also incorrect because point R is on the boundary of ∠PQR.

How many angles can be there with a common vertex?

Option 4 is correct because as there can be infinite angles made with a common vertex.
