The minimum information required to make a triangle, is any of the following
Triangle Information Complete!
You are done! You do not need to enter any more information!
Unfortunately, you cannot create a triangle with the information you have entered. To understand why this is the case, you would need to be familiar with the law of sines. In particular, read about the law of sines and no triangles .
Invalid Side Lengths
You did not yet enter 3 valid side lengths. Please enter all 3 side lengths of your triangle.
Your 3 side lengths ( ) are invalid .
Side Lengths of do not adhere to the triangle inequality theorem. which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side. Read more about this rule here.
Invalid Angle Measurements
The angle measurements that you entered are invalid. Remember the formula for the interior angles of a triangle. This rule states that the sum of the interior angles of a triangle must be exactly 180°.
I am going to change 1 of your angle's measurements from to °. To read more about this rule, click here.
