Question

ABCD is a cyclic quadrilateral such that angle A=90°,LB=70°,LC=95° and LD=105°

Answer 1

◆Ekansh Nimbalkar◆
hello friend here is your required answer
Sol.We know that opposite angles of a cyclic quadrilateral are supplementary.
Here sum of opposite angles is not.180°
LA+LC=90°+95°=185°
Hence ABCD is not a cyclic quadrilateral

Answer 2

if ABCD is a cyclic quadrilateral then sum of it's opposite angles will be supplementry
therefore,angle A +angle B =90+70=160 &also angle C + angle D=95+105=200
it shows that sum of opposite angles is not 180
hence we conclude that ABCD is not a cyclic quadrilateral...
