WebWe can use this result to prove whether a triangle is a right triangle just from its side lengths. For example, if we have a triangle with side lengths 6, 8, and 10, then we note that 10 is the longest side and we have that 1 0 = 1 0 0 and 8 + 6 = 1 0 0 ; so the triangle is a right triangle. Similarly, if we have a triangle with side lengths of 2, 3, and 4, then we …
WebA right triangle must have two sides forming a right angle, and this happens iff two of its sides are orthogonal to each other, iff the corresponding vectors' dot product (inner product) is zero.
