Phytagorean theorem. Need to calculate :
First) Hypotenuse c of right triangle if sides are a=12 and b=5.
Second) Find side b if side a is 12 and hypotenuse c=20
Third) Need to claculate side of rectangle if one side is 9 and diagonal is d=15.
Forth) Find area of isosceles ( 2 equal sides) triangle if base a=6 and height is h=4.
Its Phytagorean theorem with simple tasks and with apply to rectangle and triangle.
