Please provide 2 values below to calculate the other values of a right triangle. Right triangles, and the relationships between their sides and angles, are the basis of trigonometry. The sides of a right triangle are commonly referred to with the variables a, b, and c, where c is the hypotenuse and a and b are the lengths of the shorter sides. The altitude divides the original triangle into two smaller, similar triangles that are also similar to the original triangle. If all three sides of a right triangle have lengths that are integers, it is known as a Pythagorean triangle. In a triangle of this type, the lengths of the three sides are collectively known as a Pythagorean triple. Examples include: 3, 4, 5; 5, 12, 13; 8, 15, 17, etc. Area and perimeter of a right triangle are calculated in the same way as any other triangle. The perimeter is the sum of the three sides of the triangle and the area can be determined using the following equation:. Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above ratio.

Joe is the creator of Inch Calculator and has over 20 years of experience in engineering and construction. Table of contents: How to find the sides of a right triangle How to find the angle of a right triangle How do you solve a right angle triangle with only one side? The Law of Sines states:. However, if only two sides of a triangle are given, finding the angles of a right triangle requires applying some basic trigonometric functions:.

Triangle angle calculator is a safe bet if you want to know how to find the angle of a triangle.

FAQ How do I find angles in a triangle? Finding the missing side or angle couldn't be easier than with our great tool — right triangle side and angle calculator. Whether you have three sides of a triangle given, two sides and an angle or just two angles, this tool is a solution to your geometry problems. When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below. Here are some standard classifications: Equilateral Triangle: All three sides are of equal length, and all three angles are 60 degrees. In other words, it is the smallest circle that the triangle can fit inside of. Choose two given values, type them into the calculator, and the calculator will determine the remaining unknowns in a blink of an eye! The Law of Cosines or Cosine Rule is a generalization of the Pythagorean theorem formula that relates the lengths of the sides of a triangle to the cosine of its angles. Our Triangle Calculator is versatile and can handle various types of triangles, including scalene, isosceles, right, acute, and obtuse triangles. The Law of Cosines states:. Are all right triangles similar? The circumcenter of the triangle does not necessarily have to be within the triangle. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges.
