Inscribed Circle Construction (practice)

Explore the construction...

Construct an inscribed circle by following the construction steps provided below.

1.		Select the Polygon tool and construct a triangle. Label the vertices P, Q, and R.
2.		Select the Angle Bisector tool and construct the angle bisectors of the angles in the triangle.
3.		Create and label point A at the intersection of the three angle bisectors.
4.		Select the Perpendicular Line tool and create a line perpendicular to segment RQ and runs through point A.
5.		Create and label point B at the intersection of segment RQ and the perpendicular line.
6.		Activate the Circle tool and construct a circle with the center at point A and runs through point B.
7.		Drag each vertex to check if the construction is correct.
