An instrument used for drawing and measuring angles
A protRactor is an instrument used in geometry to define angles.
to measure the angles
to measures the angles
with a protactor......
Degrees of angles are measured with a protractor.
A Protactor is used to measure different andgle by putting the middle of the protactor ( occasionally it should have a dot on the protractor / where you want to measure) then you either measure the reading the measurements inside or out.
A protactor ,ruler, and a straightedge
with a protactor haha bt basically noone knws da answer ha ha
Metric ruler, Meterstick, Ruler,Thermometer, Weighing scale, Balance scale, Protactor.. :) JaneLizetteAguilar
universal bevel protactor is an angle measuring instrument which measures acute angle ,obtuse angle as well as it is used to layout an angle. its least count is 5 minute.
I did't read the book, but according to my information that the main character in this novel is Princess Ozma, because glinda is just a fictional character and the protactor of the princess.
Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.
using protactor, we use to draw angles in anticlockwise direction and that angles are called positive quadrant angles. and angles in clockwise direction, these angles are called negative quadrant angles.
