QUESTION: 1

In the given figure, ∠BPC = 19^{o}, arc AB = arc BC = arc CD. Then, the measure of ∠APD is

Solution:

QUESTION: 2

ABCD is a parallelogram. A circle passes through A and D and cuts AB at E and DC at F. If ∠BEF = 80^{o}, then ∠ABC is equal to

Solution:

Given, ABCD is a parallelogram and AEFD is a cyclic quadrilateral.

∠BEF=80^{∘}

Now, ∠ADC=∠BEF=80^{∘} (Angle of a cyclic quadrilateral is equal to the opposite exterior angle )

Also, now in parallelogram ABCD,

∠ABC=∠ADC=80^{∘} (Opposite angles of a parallelogram are equal)
