you will sometimes find it necessary to build walls that require advanced framing techniques —such as figuring out the wall angle under a gable roof. To accomplish this, you will be required to know how to measure a wall angle using basic geometry. Here's how to do it:
To calculate the wall angle length you will need to determine the difference between the wall's short side height and the wall's long side height. Use the formula, A2 +B2=C2. Square the length of the wall base. Square the sidewall height differences. Add these figures and determine the square root of the sum of figures added.
