WebAn angle whose measure equals 90°. obtuse angle An angle with a measure greater than 90° but less than 180°. bisector of an angle A set of points which divides the angle into two angles of equal measure. perpendicular lines Lines that intersect to form right angles. adjacent angles WebAn angle bisector is defined as a ray, segment, or line that divides a given angle into two angles of equal measures. The word bisector or bisection means dividing one thing into two equal parts. In geometry, we usually divide a triangle and an angle by a line or ray which is considered as an angle bisector.
