 A 9, 12, 15 triangle is similar to a 3, 4, 5 triangle but with sides 3 times bigger The angles will be the same and we know one will be a right angle or 90 degrees The sum of all the angles of a triangle is 180 degrees Hence 90 degrees must be the largest angle in the 9, 12, 15 triangleExample The smallest Pythagorean Triple is 3, 4 and 5 Let's check it 3 2 4 2 = 5 2 Calculating this becomes 9 16 = 25 Yes, it is a Pythagorean Triple! The triangle perimeter is the sum of the lengths of its three sides p = a b c = 7 9 13 = 29 p = abc = 7913 = 29 p= abc = 79 13 = 29 2 Semiperimeter of the triangle The semiperimeter of the triangle is half its perimeter
