# Triangle Calculator

What this calculator can do:
Solving for sides, angles and area of the triangle.

### Solving a Triangle

We can use the following concepts appropriately to figure out the sides and angles of a triangle.

 1. Sum of Angles 2. Law of Sines 3. Law of Cosines   The three angles within a triangle always total up to 180 degrees (or π radians). Using this, when given 2 angles, we can easily figure out the remaining angle. Law of Sines shows that the ratio between an angle and its opposite side is always equal within a triangle. This equation can be modified to calculate the remaining angles and sides. Law of Cosines allows the calculation of a side when given the other two sides and its opposite angle. This equation can also be modified to calculate the remaining angles and sides.

### Calculating the Area

We can use the following formulas to easily calculate the area of a triangle.

 1. Heron's Area Formula 2. Oblique Triangle Formula  Heron's Area Formula can calculate the area when the three sides of a triangle are given. Oblique Triangle Formula can calculate the area when the two sides and its adjacent angle are given.
