    Have you heard of proving two triangles congruent by SAS?

    If you draw two segments, each 4 inches long. Then make sure the angle between them is 90 degrees, does that determine a specific triangle? Has the third side become of a fixed length?

    Look at the figure above. Let's say both sides are 4 inches long and the angle between them is 90 degrees. If the two 4-inch segments and the angle between are part of a triangle, can you draw the third side of the triangle?

    The third side shown above would be it, right? There is no other way of drawing a triangle with the two 4-inch sides and the included 90 deg angle, right?

    That means you can only draw one triangle with the information you were given.
