Inscribed Circle to a Given Triangle
The three sides of the given triangle are tangential to the inscribed circle
The procedure for drawing the inscribed circle to a given triangle is as follows:
- Draw the given triangle ABC.
- Bisect any two angles of the triangle. The bisecting lines will intersect at O, which is the centre of the inscribed circle.
- Draw a perpendicular line to any side from O to meet the side at D
- With O as centre and radius OD draw the inscribed circle.
Circumscribed Circle to a Given Triangle
The circumference of the circumscribed circle to a given triangle touches the vertices of the given triangle.
The procedure for drawing the circumscribed circle to a given triangle is as follows:
- Draw the given triangle ABC
- Bisect any two sides of the given triangle.
