Let us draw the following triangles. By drawing the circum-circle in each case, let us write the position of circum-centre and the length of circum-radius by measuring it.
A right-angled triangle having two sides 4 cm and 8 cm length, containing right angle.
Steps of Construction:
1. Construct triangle of given dimensions.
2. We name the triangle as ABC.
3. Draw perpendicular bisector of AB.
4. Draw perpendicular bisector of BC.
5. The point of intersection is the circumcenter. Name it as O.
6. With O as center and OC as radius, draw a circle.
7. The circle passes through A,B and C and is thus the circumcircle of this triangle.
8. We measure the circumradius, OC = 4.47cm.
