Math calculator
Pythagorean Theorem Calculator
Find the hypotenuse, area, and perimeter of a right triangle from two legs.
Formula
Pythagorean theorem
c = sqrt(a^2 + b^2)
Legs 3 and 4 give hypotenuse 5.
FAQs
Does this work for any triangle?+
No. It assumes a right triangle.
What are a and b?+
They are the two legs that meet at the right angle.
How does the Pythagorean Theorem Calculator calculate the result?+
It uses the Pythagorean theorem: c = sqrt(a^2 + b^2). Legs 3 and 4 give hypotenuse 5.
What information do I need to use the Pythagorean Theorem Calculator?+
Find the hypotenuse, area, and perimeter of a right triangle from two legs.
How accurate is the Pythagorean Theorem Calculator?+
Pythagorean Theorem Calculator applies the formula and assumptions shown on this page. Results may be rounded for readability, so verify changing rates, thresholds, medical guidance, or legal rules with the cited source or a qualified professional.
What should I check before using the Pythagorean Theorem Calculator result?+
Check that the units, dates, rates, and assumptions match your situation. Change one input at a time to understand which values have the largest effect on the result.
