passes through the intersecting line. Then the angle unit is expressed in two types, namely

radians (rad) and degrees (°). ∠ can also be called ∠ , and the measure of the angle P is
denoted by ∠ . The measure of the angle of one complete rotation is 360°.

Determining the Size of the Angle Formed by the Clock's Hand

Watch the following video!

Angle Gauges (Arc)

You can calculate the size of the angle formed manually, you can use an angle

measuring tool, namely an arc. This tool can help Ananda measure the angle that has been
formed and form the size of the angle to be drawn.
