To bisect an angle means that we divide the angle into two equal ( congruent ) parts without actually measuring the angle. This Euclidean construction works by creating two congruent triangles . See the proof below for more on this. WebbAn inscribed angle is formed by two crossing chords and has its apex “on” the circle. The vertex of an inscribed angle is on the circle, and the sides of the angle are on two of the circle’s chords. The inscribed angle is half the length of the arc formed by the two sides cutting the circle in half. Inscribed angle = ½ x intercepted arc.
