Question

what will be the locus of three noncollinear points A, B and C which is equidistant from A ,B and C

Answer 1

Ans.)angle RQS =42° then angle RQS will also be 42°( angles on the same sent of the circle are equal)

Angle PRQ=90°( angle in the semi circle is 90°)

Then,angle PRQ+QRT=180°(linear pair)

90°+angle QRT=180°

Angle QRT=90°

Now,in triangleQRT,
