WebFor a triangle with side lengths a, b, c, the Pythagorean theorem states that if and only if a 2 + b 2 = c 2 then the triangle is a right triangle. If a is the distance between points p and q, with p = [ p 1 p 2 p 3], and q = [ q 1 q 2 q 3], then a = P − Q = ( p 1 − q 1) 2 + ( p 2 − q 2) 2 … Webone length, and one angle (apart from the right angle). Example: Depth to the Seabed The ship is anchored on the seabed. We know: the cable length (30 m), and the angle the cable makes with the seabed So we should be able to find the depth! But How? The answer is to use Sine, Cosine or Tangent! But Which One?
