SAS Triangle Calculator

MATH CALCULATOR SAS Triangle Calculator Calculate the area, perimeter, and angles of a triangle using the SAS method.
📖
What is the SAS Triangle Calculator & How does it work?
The Side-Angle-Side (SAS) method is used to calculate the properties of a triangle when two sides and the included angle are known. This method allows us to determine the area, perimeter, and angles of the triangle.
Area = frac{1}{2}absin(C)
a = side 1, b = side 2, C = included angle in degrees
To find the third side, we use the Law of Cosines: c = sqrt{a^2 + b^2 – 2abcos(C)}The perimeter is simply the sum of all sides: Perimeter = a + b + c. To find the other two angles, we can use the Law of Sines or Cosines.

Frequently Asked Questions
How do I use the SAS Triangle Calculator?
Enter the lengths of two sides (a and b) and the included angle (C in degrees). The calculator will compute the area, perimeter, and the other two angles.
What is the formula for the area of a triangle using SAS?
The area is calculated as 1/2 times the product of the two sides (a and b) multiplied by the sine of the included angle (C).
How do I find the third side of a triangle with SAS?
Use the Law of Cosines: c = sqrt(a^2 + b^2 – 2ab*cos(C)).
Can this calculator handle angles in radians instead of degrees?
No, the calculator uses degrees for the included angle. You’ll need to convert radians to degrees first.
What is the Law of Cosines used for?
The Law of Cosines is used to find the length of the third side of a triangle when you know two sides and the included angle.
How do I calculate the perimeter of a triangle using SAS?
Add up all three sides: Perimeter = a + b + c, where c is calculated using the Law of Cosines.
Is there a limit to the size of the angles or sides I can input?
The calculator accepts angles between 0 and 180 degrees. Side lengths should be positive numbers.
