Joanna has a flat wooden triangular piece as part of a wind chime. the piece is suspended by a wire anchored at a point equidistant from the sides of the triangle. where is the anchor point located?

The anchor point would be placed at the center of the triangle. In order to find this point, you have to construct three angle bisectors. Start from one vertex and intersect it to the midpoint of the opposite side. These angle bisectors are drawn in blue lines. The intersection of these bisectors, represented by the red dot, is the anchor point.

The operation is suck a c@ck? !

The variables should add up to equal 1
