Angle Bisectors
An angle bisector is equidistant from each side of an angle.
Create angle bisectors for each angle in the triangle above.
Mark the point of concurrency D.
Create a line perpendicular to segment BC through point D.
Label the point where the perpendicular intersects segment BC as point E.
Create a circle with center D and radius DE.
Incenter
Move points A, B, and C. What do you notice? Where is the point of concurrency?
