A protractor is the common tool used in mathematics for measuring and drawing angles.
A shape with a lot of sides and angles.
the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles.
A protractor (not potractor) is a tool used to measure angles in mathematics.
At right angles - in two or more dimensions.
The likely word is "geometry" (mathematics of angles and shapes).
Engineering, architecture, product design, all these areas use angles daily.
The unit for measuring angles is the degree. A right angle is 90 degrees, a full turn is 360 degrees.There is also a unit called the radian. A full turn is 2pi or 6.28... radians.
