Solution

1. Draw the base, $B C = 3.8 c m$ .
2. Construct $55^{o}$ at $B$ . Similarly, mark $45^{o}$ from $C$ . They will intersect at a point $A$ . Join $A B$ and $A C$ .
3. Construct perpendicular bisector of each side. They meet at a point $O$ . From point $O$ , keep it at any vertex of a triangle, take it as radii and draw the circumcircle
