MATH CALCULATOR
Triangle Degree Calculator
Calculate angles and sides of triangles easily using the Triangle Degree Calculator.
What is the Triangle Degree Calculator & How does it work?
A triangle is a polygon with three edges and three vertices. The sum of the interior angles of a triangle is always 180 degrees.
Using trigonometric functions such as sine, cosine, and tangent, you can calculate unknown sides or angles in a right-angled triangle when other measurements are known.
Using trigonometric functions such as sine, cosine, and tangent, you can calculate unknown sides or angles in a right-angled triangle when other measurements are known.
sin(theta) = frac{text{opposite}}{text{hypotenuse}}
theta = angle, opposite = length of the side opposite to the angle, hypotenuse = longest side of the triangle

Frequently Asked Questions
How do I find the angle of a right triangle if I know the opposite and adjacent sides?
Use the arctangent function: ΞΈ = atan(opposite/adjacent).
What is the formula to calculate the sine of an angle in a right triangle?
sin(ΞΈ) = opposite/hypotenuse.
Can this calculator help me find the length of the hypotenuse if I know the other two sides?
Yes, use the Pythagorean theorem: cΒ² = aΒ² + bΒ², where c is the hypotenuse and a/b are the other sides.
How do I calculate the cosine of an angle in a right triangle?
cos(ΞΈ) = adjacent/hypotenuse.
What if I only know one side and one angle, how can I find the other sides?
Use trigonometric functions like sine or cosine to solve for the unknown sides.
Is this calculator useful for non-right-angled triangles too?
No, this calculator is specifically for right-angled triangles. For others, use the Law of Sines or Cosines.
How do I find an unknown angle if I know all three sides of a triangle?
Use the cosine rule: cos(ΞΈ) = (bΒ² + cΒ² – aΒ²) / (2bc), where ΞΈ is the angle opposite side a.
