The parts are arm vertex and ore

You can tell if a ray is bisecting an angle if the angle is cut directly in half into two congruent parts.

Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle. Right Angle: An angle whose measure is 90 degrees is called right angle. Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle. Straight Angle: An angle whose measure is 180 degrees called a straight angle. Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle. Complete Angle: An angle whose measure is 360 degrees is called a complete angle. Zero Angle: If the measure of an angle is zero it is called a zero angle.
