If a(x1, y1), b(x2, y2), c(x3, y3), and d(x4, y4) form two line segments, ab and cd , which of these conditions needs to be met to prove that ab is perpendicular to cd?

see attachment for choices

Step-by-step explanation:

We know that,

If two line segments are perpendicular then the product of their slope is equal to -1,

Also, the slope of a line segment having the end points and is,

So, the slope of line segment AB having end points and is,

Similarly, the slope of line segment CD having end points and is,

Hence, by the above property of perpendicular line segments ,

If AB and CD are perpendicular then,

Third option is correct.

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
