Pythagorean theorum.
By using trigonometry or using Pythagoras' theorem for a right angle triangle.
A right triangle has three sides. If you label the sides connected to the right angle side A and side B, and the hypotenuse side C, A^2+B^2=C^2.

Yes simply with a protractor and a measuring device.
Pythagorean theorum.
By using trigonometry or using Pythagoras' theorem for a right angle triangle.
Use either the Sine or Cosine rules depending on the information you know about the triangle.
There is not enough information to solve this. You need to know one other length od a side to solve this.
It depends on the details of the specific triangle.
If it's a right angle triangle then use Pythagoras' theorem to find the 3rd side
Assuming that you are talking about a right triangle. a2 + b2 = c2 Solve for a a = square root of c2-b2
A right triangle has three sides. If you label the sides connected to the right angle side A and side B, and the hypotenuse side C, A^2+B^2=C^2.
Square the two smaller sides and add them together. Take the square root of the answer. If that is the same as the third side then you have a right angled triangle and if not, then you have not.
Two sides, or two angles + one side.
Given the lengths of two sides of a right triangle, you can find the length of the other side.
