It's pretty easy to find the area of a triangle as long as one takes the time to commit the equation to memory. In order to find the area, take 1/2 of the base and multiply it by the height - the equation looks like this: A=1/2b x h
To find the area of a triangle, one can compute for the square root of "s (s-a) (s-b) (s-c)" where s is half the perimeter and where a, b, and c are the length of each side. The value of area is usually expressed in the standard unit "square meters." Read more about the area of a triangle and other geometrical shapes on http://www.ask.com/wiki/Area.
There are several different methods used to find the angle of a triangle. The key is to remember that all three angles add up to 180 degrees, so if the triangle in question is equilateral then the angles must each be 60 degrees. If two of the three angles are present, simply subtract those two numbers from 180. Another option is to use a protractor.
