If the value of an angle in degree is D and in radian is R; then let us determine the value of

Let us write whether the following statements are true or false:

(i) The angle, formed by rotating a ray centering its end point in anticlockwise direction is positive.

(ii) The angle, formed for completely rotating a ray twice by centering its end point is 720°

In a circle, if an arc of 220 cm. length subtends an angle of measure 63° at the centre, then let us determine the radius of the circle.

The end point of the minute hand of a clock rotates in 1 hour

Let us write the circular value of an angle formed by the end point of hour hand of a clock in 1 hour rotation.

The circular value of each internal angle of a regular hexagon is

If the measures of two angles of a triangle are 65°56’55’’ and 64°3’5’’, then let us determine the circular value of third angle.

A rotating ray makes an angle π. Let us write by calculating, in which direction the ray has completely rotate and there after what more angle it has produced.

Let us fill in the blanks:

(i) π radian is a ______angle.

(ii) In sexagesimal system 1 radian equals to ______(approx)

(iii) The circular value of the supplementary angle of the measure is_____

radian equals to
