Inscribe a Circle Inside of a Triangle
1) Bisect TWO of the angles.
2) Use the Intersect tool
to create a point where the two angle bisectors intersect.
3) Using any of the sides, create a line perpendicular to that side that goes through the point you created in step 2.
4) Use the Intersect tool to mark the point where that perpendicular line crosses the side you chose to use.
5) Use the Compass tool
to create a circle with a radius equal to the distance between between the two points you've marked, centered at the intersection of the angle bisectors.
