Answer:
leg = √7 units (approximately 2.65 units)
Step-by-step explanation:
Given a right isoceles triangle with a hypotenuse of 14 units, the two other legs must be congruent in length. Because this is a right triangle, the pythagorean theorem a^2 + b^2 = c^2, can be used.
Since the two legs are congruent, side a = side b. This means that
2leg^2 = hypotenuse.
