The construction of a circum circle of a triangle is an important Geometry task in various Board syllabi.

Today we are going to learn this technique with the help of an animation.

However, first of all, there is a total of two stages in this type of questions in secondary level or any other examination.

The first stage is to draw a specially shaped triangle. Just as it mentioned in the question.

Then in the second stage, required the circum circle is to be drawn.

The second stage is described in this animation.

If you want to learn the first stage, that is the construction of the triangles, check out the other videos in this channel.

So, we are, now, going to draw the circum circle of the triangle, called ABC.

To draw a circum circle on a triangle, we have to draw the bisectors of any two arms of the triangle.

Let us first draw the bisector of the arm, BC.

The name of this bisector is PQ.

Then the bisector of the arm AB will be drawn.

This bisector is named RS.

These two bisectors intersect each other at point W.

So, the circum center of this triangle is W.

B is connected to W. WB is the circum radius. In this case the, instead of connecting W to B, W to C or W to A could also work.

Al last, the required circum circle can be drawn, taking W as circum center and WB as the circum radius.
