A triangle has sides of length A, B and C. C A B In this example, A is the length of the longest side. This triangle is said to be right‑angled if the following equation is true: A × A = (B × B) + (C × C) A procedure will be written to check whether three lengths represent a right‑angled triangle. The lengths will be input in any sequence. The procedure IsRA() will: • prompt and input three integer values representing the three lengths • test whether the three lengths correspond to the sides of a right‑angled triangle • output a suitable message. The length of the longest side may not be the first value input. 9 Write pseudocode for the procedure IsRA(). [5]
