The Right Angle Correction calculator computes the change in the base needed to make a right angle corner based on the height, diagonal and initial base.
INSTRUCTIONS: Choose units and enter the following:
- (W) Initial Base Width
- (H) Height
- (D) Diagonal
Right Angle Correction (x): The calculator return the base width difference needed to create a right angle corner. The length is in feet, inches and fraction. However, this can be automatically converted to other length units (e.g. meters) via the pull-down menu.
The Math / Science
A right angle corner in framing or other construction adheres to the basic math principles of right angles. A common right triangle is the 3, 4, 5 triangle where the two sides are 3 and 4 inches with a diagonal of 5 inches. This calculator lets you adjust the base width by an amount to get a right angle based on a fixed height (H) and length of diagonal (D). The formula for base correction is:
`"x" = sqrt(D*D - H*H) - W`
where:
- x = base correction length
- D = Diagonal Length
- W = Initial Width
- H = Height
