The angle shown above is 1 degree.

What is the equivalent of 1 degree expressed in turns?

Measure and classify each angle:

Measure the unknown angles $A$and $B$in degrees.

Specify whether the angle $\angle DAB$ is acute, obtuse, right, straight, or reflex angle.

Measure the unknown angles $A$ and $B$in degrees.

Construct an angle of $25°$ with the help of a protractor.

Is $75°$ an acute angle, obtuse angle, reflex angle, or complete angle?

How many degrees are there in the angle between the hour hand and the minute hand of a clock, when it is

$3$ $o\text{'}$clock?

Specify whether the given angle is acute, obtuse, right, straight, or reflex angle.

$\angle PQR$

Find the measure of the angle shown in each figure. (First estimate with your eyes and then find the actual measurement with a protractor).

Which angle has a large measure? First estimate and then measure the angle $\mathrm{A}$ and angle $\mathrm{B}$.

From these two angles which has larger measure? Estimate and then confirm by measuring them.

Measure $\angle ABC$ given in the given figure and construct an angle $DEF$ equal to $\angle ABC$.
