Yes simply with a protractor and a measuring device.
If it's a right triangle, use pythagorean's theorem (a2+b2=c2) to solve it. = If it's an oblique triangle, use the law of sines or cosines (see related link)
Pythagorean theorum.
By using trigonometry or using Pythagoras' theorem for a right angle 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
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.
