AB IS 12 because CD is 12 (rectangles have two pairs of equal sides)
BC IS 5 ^same rule above.
AC is point A connecting point C through the rectangle which is calculated by using the Pythagorean triangle theorem
You’ll see that the rectangle is split into two right triangles.
The formula for the theorem is a^2+b^2=c^2
a and b are two side lengths and c is the longest side (hypotenuse)
So in this case 5^2+12^2=c^2 where c^2 is side AC
