- Step 1: Draw a line segment OB.
- Step 2: Place the protractor at point O.
- Step 3: In the outer circle of the protractor, look for 45 degrees reading, and with a pencil mark a dot and name it A.
- Step 4: Join O and A now. Angle ∠AOB = 45°.
How do you find a 45 degree angle without a protractor?
If you need to figure out a 45-degree angle and you don't have a protractor handy, you can create a workaround. A 45-degree angle is half the size of right angle, which is 90 degrees. Working with a ruler and a square or other right angle substitute, you can make the angle without any special tools.
How is offset calculated?
If the relationship between two parameters is linear, there is a straight line that can be drawn on a graph to describe this relationship. The equation of this line will be Y = mX + b where m is the multiplier (or slope of the line) and b is the offset(or the y-intercept of the line).

How do you find the slope multiplier?
Roof Pitch Multiplier Formula Once you know your roof slope expressed as “X-in-12″ (rise-in-run), the roof pitch multiplier is determined by finding the square root of ((rise/run)² + 1). Remember that the slope of the roof provides the rise and the run to be plugged into the equation.
How is offset area calculated?
The method used for irregular shaped areas is called the "offset method". First measure the length of the longest axis of the area (line AB). ... At each of these points, measure the distance across the area in a line perpendicular to the length line at each point (lines C through G). These lines are called offset lines.
