"The Pythagorean Theorem relates the lengths of the three sides of any right triangle. The legs of a right triangle (the two sides of the triangle that meet at the right angle) are customarily labelled as having lengths a and b, and the hypotenuse (the long side of the triangle, opposite the right angle) is labelled as having length c. The lengths are related by the following equation: a ^2 + b^2= c ^2. refer to http://www.purplemath.com/modules/pythagthm.htm for details.

This equation allows you to find the length of a side of a right triangle when theyve given you the lengths for the other two sides, and, going in the other direction, allows you to determine if a triangle is a right triangle when theyve given you the lengths for all three sides.

This equation can alternatively be written as c = sqrt of (a^2+b^2). You can find the square root of a number by calling the standard function Math.sqrt. For example, the statement double y = Math.sqrt(x) sets y to the square root of x.

I.Given the right triangles described below, write a program to compute the lengths of the remaining sides using a program.

a. a = 48 and c = 80

b a = 84 and c = 91

II.Determine if the following triangles are right-angled triangles:

a. a = 45, b = 55, and c = 75

b. a = 28, b = 45, and c = 53
