(1) Incidentally, this formula shows that the sum of the angles of a spherical triangle must be greater than or equal to π, with equality holding in case the triangle has zero area.

Learn what the areas of triangles and rectangles are. Learn how to find the area of a triangle or a rectangle by discovering the formulas for their areas. See examples.

Learn how to find the area of a triangle with the law of sines, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.

Heron's formula yields the area of the triangle, which can then be plugged into the formula for the area of a triangle to find the height.

The formula for finding the area of a triangle is A = ½ bh. This means that we multiply ½ times the base of the triangle (b) times the height of the triangle (h) to get the area of the triangle (A).
