Inscribed Circle to a Given Triangle

Geometric Construction: Triangle - Types of triangle - 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:

  1. Draw the given triangle ABC.
  2. Bisect any two angles of the triangle. The bisecting lines will intersect at O, which is the centre of the inscribed circle.
  3. Draw a perpendicular line to any side from O to meet the side at D
  4. 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.

Geometric Construction: Triangle - Types of triangle - Circumscribed circle to a given triangle

The procedure for drawing the circumscribed circle to a given triangle is as follows:

  1. Draw the given triangle ABC
  2. Bisect any two sides of the given triangle.
