Math relating to slopes (*_*）

Question

make use of a structure. For rectangle ABCD, two vertices are A ( -2,3) and B (4, 6). find the slopes of angles BC , CD , DA . Explain your answer

Answer 1

IF it's a rectangle, all angles = 90 degrees or pi/2 radians, regardless what the vertices are

the slope from A to B is (6-3)/(4+2) = 3/6 = 1/2

that would be true for 2 angles

the other two would have slopes that are the negative inverse of 1/2 or -2
