AC = 116
AC < BC < AB
How do you find the missing side of a triangle?
- Refresh the calculator. Pick a option you want. Assume that we have 2 sides and we need to find all angles. The default option is the right one.
- Enter the side lengths. Our right triangle has the hypotenuse = to 13 in and the leg a = 5 in.
- Missing side or angles appear. In our example, b = 12 in, α = 67.38° or B = 22.62°.
What is the sum of the angles of a triangle?
1 common property about triangles is that all 3 interior angles add up to the 180 degrees. This now brings us to the important theorem in geometry known as Triangle Angle Sum Theorem. According to this Triangle Angle Sum Theorem, a sum of the 3 interior angles in the triangle are always 180°
Given,
BC = 118
AB = 63*2 = 126
AC = 360 - (BC+AB)
AC = 360 - (118+126) = 116
