Answer:

Step-by-step explanation:
Given



Required
Find Y
To do this, we make use of the mid-point formula
i.e.

WX and ZY are the diagonals of the parallelogram.
The mid-point of WX is:


The mid-point of ZY is:

Equate both values of M

Multiply both sides by 2

By comparison:








Hence:

A right triangle has the two legs that form an angle of 90°, which means that the two legs are perpendicular.
In order to prove that FGH is a right triangle, you need to calculate the slopes of the lines passing through its vertexes and see if there is a pair of opposite reciprocals:
m = (y₂ - y₁) / (x₂ - x₁)
m(FG) = (-9 - 4) / (5 - 2) = -13/3
m(FH) = (-4 - 4) / (-3 - 2) = 8/5
m(HG) = (-4 -(-9)) / (-3 - 5) = -5/8
Since m(FH) and <span>m(HG) are opposite reciprocals, FH is perpendicuar to HG and FGH is a right triangle.</span>
