ABC and ADBC are two isosceles triangles on the same base BC and vertices A and D are on the
same side of BC (see Fig. 7.39). If AD is extended
to intersect BC at P, show that
(1) ΔΑΒDΔΑCD
(ii) ΔΑΒΡΔΑCP
(i). AP bisects Z A as well as D.
(iv) AP is the perpendicular bisector of BC.

AND FOR A CLEAR QUESTION REFER TO THE PIC GIVEN ABOVE.

answer: are you

step-by-step explanation:

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
