First Test, %287%2Asqrt%283%29%29%5E2%2B21%5E2=%2814%2Asqrt%283%29%29%5E2;
Is this true or is this false? This if true means that the angle made by the 21 unit and the 7%2Asqrt%283%29 unit would be 90 degrees.

In case that were true, then next consider the ratio of 7%2Asqrt%283%29 to 14%2Asqrt%283%29. What is it? 1%2F2? What does that suggest to you?
