A triangle with h representing the height and b representing the base. The equation uppercase A = one-half b h is to the right of the triangle. Set up the equation for the area of a triangle in you graphing calculator. Define the variables and use the sliders to find the areas of the triangles below.

b = 19; h = 14;
A =
⇒ 133
b = 13; h = 11;
A =
⇒ 71.5
b = 7; h = 9;
A =
⇒ 31.5
b = 2; h = 1; A =
