About the Pythagorean Theorem Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
c = sqrt(a^2 + b^2)
a = sqrt(c^2 - b^2)
b = sqrt(c^2 - a^2)
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: c = sqrt(a^2 + b^2) a = sqrt(c^2 - b^2) b = sqrt(c^2 - a^2) Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Staircase Ramp Length
Inputs
With Solve For = c, Side a = 9 and Side b = 40 as the stated inputs, the result is Missing Side = 41, Triangle Area = 180 sq units and Triangle Perimeter = 90 units. Each value corresponds to the declared output fields.
Example 2: Room Diagonal — TV Viewing Distance
Inputs
With Solve For = c, Side a = 15 and Side b = 20 as the stated inputs, the result is Missing Side = 25, Triangle Area = 150 sq units and Triangle Perimeter = 60 units. Each value corresponds to the declared output fields.
Example 3: Diagonal Fence Post — Squaring a Layout
Inputs
With Solve For = c, Side a = 6 and Side b = 8 as the stated inputs, the result is Missing Side = 10, Triangle Area = 24 sq units and Triangle Perimeter = 24 units. Each value corresponds to the declared output fields.
Example 4: Check if Triangle is Right
Inputs
With Solve For = check, Side a = 5, Side b = 12 and Side c = 13 as the stated inputs, the result is Missing Side = 13, Triangle Area = 30 sq units and Triangle Perimeter = 30 units. Each value corresponds to the declared output fields.
