Constructions 4 - Angle Bisectors

To construct an angle bisector we need two points equidistant from the vertex of the angle on the sides of the angle and to bisect the imaginary line connecting those two points.

Bisect the given angle

Bisect the given angles

Construct the Perpendicular Bisector of Segment XY

Construct a 45 Degree Angle

Duplicate Triangle MSE with the Given Angle Measure and Side Lengths (Points M, M1 and M2 are all supposed to be just M)

Duplicate Triangle RAT with the Given Side Lengths (Points R and R1 are the same, Points T and T1 are the same)

Bisect all the angles in Triangle WAM *Notice the new tool ;)

What did you notice about the 3 angle bisectors above?
