Answer:
The formula of the area of a triangle is A = (1/2) x b x h.
A = area
b = base width
h = height of the triangle
The formula for the perimeter of a triangle is p = a + b + c.
p = perimeter
a = side 1
b = side 2
c = side 3
The sum of the interior angles of a triangle will always equal 180 degrees.
