Answer the 17th question."DON'T SEND THE SIMILAR QUERY,KINDLY PERFORM THE CORRECT AND STEP BY STEP CALCULATION". PQ bisect each other (1) Q c (2) 15. ABCD is a square. A is joined to a point P on BC and D is joined to a point Q on AB If AP DQ prove that AP and DQ are perpendicular to each other. ABP DAQ = ZADQ. But z BAD = 900 ZPAD + z ADQ = 900. 16. If P and Q are points of trisection of the diagonal BD Of a parallelogram ABCD. prove that CQ II AP. Hint:A ABP ACDQ. 17. A transversal cuts two parallel lines at A and B. The two interior angles at and so are the two interior angles at B; the four bisectors form a ACBD Prove tha t (i) ACBD is a rectangle. (ii) CD is parallel to the original parallel lines. MATHEMATICS
