WebNov 2, 2024 · Perimeter = a + b + c. Also, note that you will need the table below when making use of the trigonometric functions: For example, if you are using the tan B formula and calculating its value to be 1, then by looking at the table above, you will know that the value of the angle in question is to be 45°. WebFeb 2, 2024 · How do I find the area of a right triangle given sides? The method depends on which sides you're given: If you know the two legs, then use the formula area = a × b / 2, where a, and b are the legs. If you know one leg a and the hypotenuse c, use the formula: area = a × √ (c² - a²) / 2.
