Acute Angle – positive angle measuring between 090 degrees. 5. Right Angle – measures 90 degrees. 6. Straight Angle – a line with measure of 180 degrees 7. Obtuse Angle – a positive angle measuring more than 90 degrees. 8. Quadrant/Quadrantal Angle – Angles that divide the coordinate system into quadrants. An angle is in standard position if its vertext5 is at the origin and its initial side is the positive x axis.
