WebRemember to look carefully at which angle you are being asked to name. The obtuse angle is the smaller angle. It is more than 90° and less than 180°. The smaller angle is an Obtuse Angle, but the larger angle is a Reflex Angle. If you choose the larger angle you have a Reflex Angle (more than 180° but less than 360°) instead: WebMeasuring reflex angles isn't that tough if you follow three simple steps. Place the protractor upside-down, measure the exterior of the angle, and subtract it from 360° to obtain the measures of the reflex angles in this PDF worksheet.
