Example:
1) In a right triangle, one leg is of length 1/2 and the other is of length sqrt(3)/2. What is the length of the hypotenuse?

Solution:
Since the triangle is a right trianlge, we use the Pythagorean Theorem with 
a = 1/2 and b = sqrt(3)/2 to find the length c of the hypotenuse.  Thus,
c2 = a2 + b2
c2 = (1/2)2 + (sqrt(3)/2)2
c2 = 1/4 + 3/4 = 1
c = 1         
Thus, the hypotenuse has length of one unit.
