the diagram at right. Based on the information below, what statement can you make about the relationships between the lines? Be sure to justify each conclusion. Remember: each part below is a separate problem. Homework Help ✎
p = h
w = k
r = q
z + k = 160°
When do alternate interior angles have equal measures?
If p = h, then l and m are parallel.
If two angles which form a straight angle are equal, what must their measures be?
n is perpendicular to m because w and k are both 90°.
Under what circumstances are vertical angles equal?
Is there anything special about angles that add up to 160°?
