Reverse Hypotenuse Formula
The following formula is used to calculate the Reverse Hypotenuse.
S2 = SQRT( H^2-S1^2)
- Where S2 is the length of the unknown side
- H is the hypotenuse
- S1 is the length of the known side
How to Calculate Reverse Hypotenuse?
The following example problems outline how to calculate Reverse Hypotenuse.
Example Problem #1:
- First, determine the hypotenuse.
- The hypotenuse is given as: 50.
- Next, determine the length of the known side.
- The length of the known side is provided as: 20.
- Finally, calculate the Reverse Hypotenuse using the equation above:
S2 = SQRT( H^2-S1^2)
The values given above are inserted into the equation below and the solution is calculated:
S2 = sqrt( 50^2-20^2) = 45.825
Example Problem #2:
For this problem, the variables required are provided below:
hypotenuse = 30
length of known side = 10
Test your knowledge using the equation and check your answer with the calculator above.
S2 = SQRT( H^2-S1^2) = ?
