Can I enter decimals?
Yes. The calculator works with whole numbers or decimals so you can enter metric or imperial dimensions.
Step-by-step walkthrough
Right Triangle Solver Guide
Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.
Before you start
Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.
- right triangle
- pythagorean
- hypotenuse
Detailed procedure
Step 1
Measure both legs (sides that form the right angle) in the same unit.
Step 2
Enter those values and optionally adjust decimal precision.
Step 3
Read the full triangle solution—hypotenuse, area, perimeter, altitude, and acute angles.
Teaching & troubleshooting tips
What if I only know the hypotenuse?
Provide both legs for a full solution. If you know a hypotenuse and one leg, solve for the other leg with a² + b² = c² before pasting those values here.
