Perimeter of Right Triangle Calculator. Once you have the triangle's height and base, plug them into the formula: area = 1/2(bh), where "b" is the base and "h" is the height. Ads. A right triangle is a special case of a triangle where 1 angle is equal to 90 degrees. Using the Pythagorean Theorem we get or and the area is An equilateral triangle has three congruent sides. Because the right triangle legs are perpendicular to each other, one leg is taken as a base and the other is a right triangle height: area = a * b / 2. edge a = units: edge b = units: edge c = units: angle A = degrees: angle B = degrees: area = square units: Remember: Appropriate units need to be attached. Uses Heron's formula and trigonometric functions to calculate area and other properties of a given triangle. By using this website, you agree to our Cookie Policy. Trigonometric functions: sin (A) = a/c, cos (A) = b/c, tan (A) = a/b. select elements \) Customer Voice. Explanation: . The area of such a triangle is calculated by the formula: the product of two legs divided by two. To learn how we use any data we collect about you see our privacy policy. The most important thing … Area of a triangle. Use this calculator to easily calculate the area of a triangle by the different possible pieces of information. Using information about the sides and angles of a triangle, it is possible to calculate the area without knowing the height. select elements. This calculator also finds the area A of the right triangle with sides a and b. Angles are calculated and displayed in degrees, here you can convert angle units. There is in depth information about the formulas used below the form. area = (a * b) / 2. FAQ.

Contact | A right-angled triangle is a triangle that has one right angle (equal to 90 degrees), or a rectangle with a diagonal drawn, which will divide it into two rectangular triangles. This website uses cookies to ensure you get the best experience. area = (a * b) / 2 A right triangle is a triangle that has one angle equal to 90 degrees. The sides adjacent to the right angle are called legs (or catheti, singular: cathetus). The side opposite the right angle is called the hypotenuse (side c in the figure). Right Triangle Calculator. . In the case of a right triangle a 2 + b 2 = c 2. A right-angle triangle with a base of 1 units and a height of 1 units has an area of 0.5 square units. significant figures. You may also like.
