A drafting triangle is a precision drafting tool for drawing lines at specific angles. Angles are measured in degrees. A full circle is the basis for the measurement of degrees. A circle has 360°. A right angle is formed by two lines that mark off one-quarter of a circle, or 90°. A drafting triangle always has one right angle 90°. This makes it possible to put a triangle against a T-square to draw vertical lines. There are two types of drafting triangles a 30° /60° triangle and a 45°/90° triangle. To draw a line with either triangle hold it firmly against the blade of the T -square or parallel rule with your opposite hand then draw a line by moving a pencil along the edge of the triangle.
