Non-right Triangle Equation:
From: | To: |
The non-right triangle equation \( a = \frac{c \times \sin A}{\sin C} \) is derived from the Law of Sines and allows calculation of unknown sides in oblique triangles (triangles without a right angle).
The calculator uses the equation:
Where:
Explanation: The equation is derived from the Law of Sines which states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides and angles in a triangle.
Details: These calculations are essential in various fields including engineering, physics, navigation, and architecture where non-right triangles commonly occur.
Tips: Enter known side length (c) and its opposite angle (C), plus the angle opposite the side you want to find (A). All values must be positive numbers.
Q1: What if I have two sides and one angle?
A: You can rearrange the equation to solve for unknown angles instead of sides.
Q2: Does this work for right triangles?
A: Yes, but right triangles have simpler relationships (Pythagorean theorem, SOHCAHTOA).
Q3: What units should I use?
A: Any consistent length units for sides (cm, m, inches, etc.) and degrees for angles.
Q4: What if my angles don't add up to 180°?
A: The calculator assumes valid triangle angles. Ensure your angles sum to less than 180°.
Q5: Can I use radians instead of degrees?
A: The calculator currently uses degrees, but the formula works with radians if converted properly.
