Trig radians: introduction

Learning Material  |  Interactive Lesson

Published on 2018 August 13th

Use radians to measure angles. Identify key angles in their radian form, for example ?/6=30°. Convert angles in degrees (up to 360) to angles in radians. Solve measurement problems using angles in radians. Determine arc lengths using radians. This learning object is one in a series of seven objects. Three objects in the series are also packaged as a combined learning object.
Students identify that a radian is the angle at the centre of any circle when the arc length equals the radius of the circle.
Students convert angles in degrees to radians.
Students identify selected angles in radians and their equivalents in degrees.
Students solve problems by measuring angles using radians as an alternative to degrees.
