We can draw a 45-degree angle by using the following steps:

  1. Step 1: Draw a line segment OB.

  4. Step 4: Join O and A now. Angle ∠AOB = 45°.

How do you find the angle?

For the exact angle, measure the horizontal run of the roof and its vertical rise. Divide the horizontal measurement by the vertical measurement, which gives you the tangent of the angle you want. Use a trigonometry table to find the angle.
