Question

AB=5cm <A=50* <B=70* construct a circumcircle

Answer 1

Draw triangle ABC with the given measurements.



Step 2 :

Construct the perpendicular bisectors of any two sides (AC and BC) and let them meet at S which is the circumcentre.



Step 3 :

With S as center and SA = SB = SC as radius draw the circumcircle to pass through A, B and C.



In the above figure, circumradius  =  3.2 cm.

From the steps of construction of circmucircle, first we have to know, how to construct perpendicular bisector. 

So, let us see, how to construct perpendicular bisector.
