Question 1

Does the theorem work with all triangles?

Accepted Answer

No. The Pythagorean theorem ONLY works with right triangles (those that have a 90-degree angle). If the triangle doesn't have a right angle, you cannot use this formula.

Question 2

Can I use decimals in the calculator?

Accepted Answer

Yes, the calculator accepts decimal numbers. You can enter values like 3.5, 12.75, or 0.8. Results will be shown with two decimal places of precision.

Question 3

How do I know which side is the hypotenuse?

Accepted Answer

The hypotenuse is ALWAYS the longest side of the right triangle and is the side opposite the 90-degree angle. The other two sides are called legs.

Question 4

What do I do if I get an error in the calculator?

Accepted Answer

The calculator requires exactly TWO values to work. If you enter fewer than two or all three values, it will show an error. Additionally, all values must be greater than zero.

Question 5

Why don't my manual calculations match exactly?

Accepted Answer

Small differences are usually due to rounding. The calculator uses high precision internally and only rounds the final result. If you calculate manually with rounded decimals at each step, you may get a slightly different result.

Question 6

Can I use different units for each side?

Accepted Answer

No. All sides must be in the same unit of measurement. If you have one side in meters and another in centimeters, you must convert them to the same unit first before using the calculator.
