Well the assignment is pretty self explanatory. After you read the triangles apply the Pythagorean theorem.

int a = // read the angle
int b = // read the angle
int c = // read the angle

// if a*a + b*b is equal to c*c then it is a right angle triangle

Then use System.out.println() statements to print the result according to the assignment.
