Cleaver (geometry)

The cleavers and Spieker center of a triangle

In geometry, a cleaver of a triangle is a line segment that bisects the perimeter of the triangle and has one endpoint at the midpoint of one of the three sides.

• Each cleaver is parallel to one of the angle bisectors of the triangle.^[1]
• The three cleavers concur at the center of the Spieker circle.
