In Figure,PQAB and PRBC. If /_QPR=102^(0), determine /_BAC .Give reasons.

In Fig.11.31,PQ=PR and SQ=SR. Prove that /_PQS=/_PRS

In the given figure, PQ||AB and PR||AC . Prove that QR||BC

In Fig.10.101,PQ and PR are two tangents to a circle with centre O. If /_QPR=460 then /_QOR equals (FIGURE) 67o (b) 134o (c) 44o ( ) 46o

In Fig. 1, ABC is a triangle in which AB = BC and /_B = 40^@ , then x=

In Fig. (ii), AD = BC and AD || BC. IS AB = DC? Give reasons in support of your answer.Hint. Prove that /_\ ABC = /_\ CDA .
