Answer

Angles are measured in degrees. The symbol for degrees is a little circle.The $ \text{FULL CIRCLE}$ is $360^\circ (360$ degrees$).$
A half circle or a straight angle is $180^\circ .$
A quarter circle or a right angle is $90^\circ .$
Place the midpoint of the protractor on the $ \text{VERTEX}$ of the angle.
Line up one side of the angle with the zero line of the protractor $($where you see the number $0).$
Read the degrees where the other side crosses the number scale.
$i.\ $Measure the angles.
$ii.\ $Measure the angles. Label each angle as acute or obtuse.
$iii.\ $Tasha measured an acute angle, and got $146^\circ . $ The teacher pointed out that she had read the wrong set of numbers on the protractor.
What is the correct angle measure for the angle she measured?
$iv.\ $Measure the following angles using your own protractor. If you need to, make the sides of the angles longer with a ruler.
$v.\ $Draw four dots, and connect them so that you get a quadrilateral.
Measure all the angles of your quadrilateral. Then add the angle measures.
Did you get $360$ degrees, or close?
