Construct an Acute Triangle ABC.
AB = BC = AC =
AB + BC + AC = (Let "s" equal the sum of the sides divided by 2.)
s= (s - AB) = (s - BC ) = (s - AC) =
Multiply s(s - AB)(s - BC)(s - AC) =
Take the square root of this value =
How does this final value compare with the area of the triangle from the computer?
Construct an Obtuse Triangle ABC.
Choose each vertex; construct polygon interior; measure Area =
If you know the lengths of the sides of a triangle, you can use Heron's formula to find the area.
Let AB = a, BC = b, and AC = c.
