Question

The following ordered pairs form pilygon wxyz:
W(-1, 3),X(2,3),Y(3,-1), and Z(-1,-1)
Identify which line segment pairs are perpendicular and which are parallel?

Name the angles that are right, obtuse and acute.

Answer 1

The picture gives all the answers. WZ (vertical because W and Z have same x coords) and ZY (horizontal because Z and Y have same y coords) are perpendicular, WX and ZY are parallel because they are both horizontal (same endpoint y coords), angles W and Z are right angles, X is obtuse and Y is acute.
