Construct the circumcentre of the \(\Delta ABC\) with \(AB = 5 \ cm\), \(\angle A = 60^\circ\) and \(\angle B = 80^\circ\). Also draw the circumcentre and find the circumradius of the \(\Delta ABC\).
Construction:
Step 1:
Step 2:
Step 3:
The circumradius is \(cm\).
(Note: Enter the answer in one decimal place)
Answer variants:
\(S\) as centre and \(SA = SB = SC\) as radius, and draw the circumcircle to passes through \(A\), \(B\) and \(C\)
Construct the perpendicular bisector of any two sides \((AC\) and \(BC\)) and let them meet at \(S\) which is the circumcentre
Draw the triangle \(ABC\) using the measurements \(AB = 5 \ cm\), \(\angle A = 60^\circ\) and \(\angle B = 80^\circ\)
