With the help of a protractor draw the following angle:

$135°$, on the right

The wheels of a car are of diameter $80 \mathrm{c}\mathrm{m}$ each. How many complete revolutions does each wheel make in 10 minutes when the car is traveling at a speed of $66 \mathrm{k}\mathrm{m}$ per hour? $\left(\mathrm{use} \pi =\frac{22}{7}\right)$

Only one circle can be drawn through three non collinear points.

In the given figure, $AB\parallel CD, \angle ABO=40°$ and $\angle CDO=35°$. Then the value of $x$ will be

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

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

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

$\angle PQR$

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

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

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

Measure and classify each angle:
