The side of an angle from which the rotation begins

• Initial Side

• Longest side

• Terminal Side

• Short side

An angle in standard position whose terminal side lies along one of the axes

• Obtuse Angle

• Quadrantal Angle

• Standard angle

• Acute angle

The location of the angle such that vertex lies at the origin and its initial side lies on the positive 'x'-axis

• Standard Position

• Original

• Standard form

• Traditional

The side of the angle after rotation

• Side Angle Side

From point A, Andre observe an antenna with 30⁰ angle of elevation. Then, Andre move 12 m closer to the antenna and stop at the point B. From point B he could see the antenna with 45⁰ angle of elevation. The height of the antenna is... m

Angles that are in standard position are said to be if their terminal side coincides with a coordinate axis

• Angle in standard position

• Quadrantal

• angle

• Angle Location
