How To Draw A Circle In A Triangle

In drawing a circle inside a triangle, also called how to inscribe a circle in a triangle to touch the three sides of the triangle. The method I’ll be sharing with you works with any type of triangle either equilateral, scalene, right-angle triangle, etc. To get started, make sure you have your drawing tools.

Here is a step by step guide on how to draw a circle in a triangle:

Step 1: Draw the given triangle

Step 2: Use your compass to bisect two of the angles.

Step 3: Note the point of intersection of the lines dividing the two angles

Step 4: From the point of intersection of the bisector of the angles (which is the center of the circle to be drawn), draw a vertical line.

Step 5: The length of the vertical line is the radius of the circle.

Step 6: With the length of the vertical line, draw the circle which will touch all three sides of the triangle.
