WebIf we know the length of any two sides and perimeter of the triangle, then we can easily find the length of the third side. Example: The perimeter of a triangle ABC is 150 cms and the length of the two sides AB and BC is 50cm and 60 cms, respectively. Then, find the length of the third side. Solution: Given, perimeter = 150 cms. AB = 50cm. BC ... WebCalculating a length The three trigonometric ratios can be used to calculate the length of a side in a right-angled triangle. Example Calculate the length AB. Give the answer to one...
WebThe Pythagorean theorem only works if you know two sides. If you only know one side and the triangle has been drawn accurately to scale, you might be able to get away with using a protractor and a ruler, but that again relies that you have the triangle actually drawn out and that it is to scale. WebFeb 24, 2024 · If it’s a right triangle, you can use the Pythagorean theorem (a2 + b2 = c2) to find the length of the missing side. From there, you …
WebFeb 20, 2024 · To find the perimeter of a triangle knowing its three sides (SSS triangle), all you have to do is add the three known sides. For example, the perimeter of a triangle with sides a = 3 cm, b = 2 cm and c = 4 cm can be calculated as follows: perimeter_SSS = a + b+ c perimeter_SSS = 3 cm + 2 cm + 4 cm perimeter_SSS = 9 cm
