Construct an isosceles triangle \(PQR\) where \(PQ = PR\) and \(\angle Q = 50^\circ\), \(QR = 7 \ cm\). Also draw its circumcircle.
Construction:
Step 1:
Step 2:
Step 3:
The circumradius is \(cm\)
(Note: Enter the answer in one decimal place)
Answer variants:
Construct the perpendicular bisector of any two sides \((QR\) and \(PR\)) and let them meet at \(S\) which is the circumcentre
\(S\) as centre and \(SP = SQ = SR\) as radius, and draw the circumcircle to passes through \(P\), \(Q\) and \(R\)
Draw the triangle \(PQR\) using the measurements \(PQ = PR\), \(\angle Q = 50^\circ\) and \(QR = 7 \ cm\)
