Notice the sides of a triangle have a certain degree of gradient or slope. We can use the slope calculator to determine the slope of each side. In a right triangle, the sides that form the right angle will have slopes whose product is -1. The formula for slope, if you wish to calculate by hand, is: (y₂ - y₁)/(x₂ - x₁) So if the coordinates are (3,6) and (7,10), the slope of the segment is (10-6)/(7-3) = 1. If the slope of the other segment forming the angle is -1, then the lines would be perpendicular since 1 × -1 = -1. Therefore, the triangle is a right triangle. You can also figure out the missing side lengths and angles of a right triangle using the right triangle calculator. If the angles given in the problem are in degrees and you want to convert to radians or radians to degrees, check out our angle converter. There is an easy way to convert degrees to radians and radians to degrees. If the angle is in radians: If the angle is in degrees: Sometimes you may encounter a problem where two or all three side lengths missing. In such cases, the Pythagorean theorem calculator won't help – you will use trigonometric functions to solve for these missing pieces. Don't worry! We have an excellent trigonometric functions calculator available for you. Chloe L. asked • 11/28/21
