    • Using the Base and Height. Download Article 1 Find the base and height of the triangle. The base is one side of the triangle. The height is the measure of the tallest point on a triangle.
    • Using Side Lengths. Download Article 1 Calculate the semiperimeter of the triangle. The semi-perimeter of a figure is equal to half its perimeter. To find the semiperimeter, first calculate the perimeter of a triangle by adding up the length of its three sides.
    • Using One Side of an Equilateral Triangle. Download Article 1 Find the length of one side of the triangle. An equilateral triangle has three equal side lengths and three equal angle measurements, so if you know the length of one side, you know the length of all three sides.
    • Using Trigonometry. Download Article 1 Find the length of two adjacent sides and the included angle. Adjacent sides are two sides of a triangle that meet at a vertex.
