Find the length of the triangle's base and height, multiply them together, and divide the product by two to find the area. Find the length of all sides of the triangle or the length of two sides and the angle between those two sides if the base and height are unavailable.


An online right triangle calculator is a program that calculates the unknown side lengths or angle measurements. It uses the known side length and angle measurements for its calculations.


The area of a triangle can be calculated from its vertices by using a formula to find the distances between them. This allows for the calculation of the area of a parallelogram with the same base and height as the triangle. Then, this figure is divided by two.


The length of a leg can be measured using radiography or by using a tape measure to determine the length between two predetermined points while the person is standing. The measurement method is chosen depending on the degree of accuracy needed.


The formula for calculating the length of one side of a right-angled triangle when the length of the other two sides is known is a2 + b2 = c2. This is known as the Pythagorean theorem.


Several types of triangles exist, including scalene, isosceles, equilateral, right, obtuse and acute. Triangles are categorized according to their sides, angles or a combination of both.


The hypotenuse of a right triangle is calculated by finding the square root of the sum of the squares of the triangle's legs. It can be expressed using the formula c = √(a2 + b2), where a and b represent the legs of the triangle and c indicates the hypotenuse.


The area of a triangle is found by multiplying one-half times its base times its height. According to Wolfram Mathworld, Beyer and Baker there are 110 formulas for the area of a triangle.


In order to find the length of a curved line, or arc length, it is necessary to know the function of the line. Once this is determined, differentiate the function, plug the equation into the arc length formula, and then integrate the formula.


An isosceles triangle has two side lengths that are equal and a remaining side that is of a different length. The two interior angles that are opposite these sides are equal to each other. The unequal side length of an isosceles triangle is called the base.
