Right Triangle Formulas:
From: | To: |
Definition: This calculator computes the lengths of the sides (a and b) of a right triangle when given the hypotenuse and one angle.
Purpose: It helps in geometry, trigonometry, and various engineering applications where right triangle calculations are needed.
The calculator uses the trigonometric formulas:
Where:
Explanation: The hypotenuse is multiplied by the cosine of the angle to get the adjacent side, and by the sine to get the opposite side.
Details: These calculations are fundamental in construction, navigation, physics, and computer graphics for determining distances and angles.
Tips: Enter the hypotenuse length (must be > 0) and angle (must be between 0° and 90°). The calculator will compute both sides.
Q1: What if my angle is exactly 0° or 90°?
A: At 0°, side a equals the hypotenuse and side b equals 0. At 90°, side b equals the hypotenuse and side a equals 0.
Q2: Can I use this for non-right triangles?
A: No, this calculator is specifically for right triangles. For other triangles, use the Law of Sines or Cosines.
Q3: What units should I use?
A: The calculator works with any consistent units (meters, feet, etc.), but results will be in the same units as your input.
Q4: How precise are the results?
A: Results are precise to 3 decimal places, but remember that real-world measurements have their own limitations.
Q5: What if I know two sides but not the hypotenuse?
A: Use the Pythagorean theorem (\( hyp = \sqrt{a^2 + b^2} \)) to find the hypotenuse first.
