Good Question! First, multiply the base x height. Then, divide the answer by 2.
Yes, those three numbers could represent the angles of a triangle, since their sum is 180.
They are call Pythagorean triples as for example 3, 4 and 5
No. In order to be the sides of a right triangle, the square of one of the numbers must be the sum of the squares of the other two numbers. (the square of 9) + (the square of 10) = 181 but (the square of 15) = 225 .
