Can you use a ruler as a protractor?
A protractor is the usual tool for the job. When a protractor is not available, however, an ordinary ruler and a calculator will suffice.
Can you use a compass as a protractor?
Along with a ruler, they are the tools most students are expected to master. Once the basic techniques are understood, you can use a compass and protractor for many different purposes, including drawing regular polygons, bisecting lines and angles, and drawing and dividing circles.
How do you mark an angle without a protractor?
Bisecting angles without a protractor
- Place the compass on the vertex of the angle (point B). Draw an arc across each arm of the angle.
- Place the compass on the point where one arc crosses an arm and draw an arc inside the angle.
- Use a ruler to join the vertex to the point where the arcs intersect (D).

How do you make a 45 degree angle without a protractor or compass?
Explanation:
- Draw a line segment BC of any length.
- Taking B as the center, construct a semicircle that bisects BC at point P.
- From P, construct three arcs dividing the semi-circle into 3 equal parts that are 60? each.
- Mark the points as x and y where the arcs bisect the semi-circle.
What is bevel protractor?
A bevel protractor is a graduated circular protractor with one pivoted arm; used for measuring or marking off angles. Sometimes Vernier scales are attached to give more precise readings.The bevel protractor is used to establish and test angles to very close tolerances.
How do you make an angle tester?
Solution
- you need the following materials; cardboard strips, drawing pins, or split pins.
- Take two cardboard strips of the same size.
- Join their one ends with the help of the drawing pin or split pin.
- Move the strips from the joint so that they can freely rotate. Your angle tester is ready.
Whats the difference between a compass and a protractor?
A protractor can be used to measure angles as well as draw angles of a specific measure. A compass constructs circles and copies segments without measuring.

In this geometry lesson, you’re going to learn all about SohCahToa. It’s probably one of the most famous math mnemonics alongside PEMDAS.
It’s defined as:
- SOH: Sin(?) = Opposite / Hypotenuse.
- CAH: Cos(?) = Adjacent / Hypotenuse.
- TOA: Tan(?) = Opposite / Adjacent.
