Calculate the length AB. Thus, in this type of triangle, if the length of one side and the side's corresponding angle is known, the length of the other sides can be determined using the above ratio. a = 3 and b = 4 the length of c can be determined as: c = a2 + b2 = 32+42 = 25 = 5 It follows that the length of a and b can also be determined if the lengths of the other two sides are known using the following relationships: a = c2 - b2. Review your formulas like the area formula, Pythagorean Theorem, and the Law of Sines, and the Law of Cosines, and you will be well equipped to find the length of any triangle! The triangle on the right is missing the bottom length, but you do have the length of the hypotenuse. WebFind the length of the missing side calculator Finding the missing side of a right triangle is a pretty simple matter if two sides are known. Step 2: Find side lengths that are parallel to the missing side. For instance, to find leg b, rearrange the Pythagorean theorem to solve for b by subtracting a from both sides. If two angles are known and the third is desired, simply apply the sum of angles formula given above.
