The given triangle is a right triangle
<h3>The length and slope</h3>
The coordinates are given as:
D (0,n), E(m,n), F(m,0)
The length is calculated using:

So, we have:



The slope is calculated using:

So, we have:



<h3>The coordinates of the midpoints</h3>
This is calculated using

So, we have:



<h3>The type of triangle</h3>
In (a), we have:
<u>Lengths</u>



<u>Slope</u>



The sides are not equal.
However, the 0 and the undefined slope implies that the triangle is a right triangle because the sides are perpendicular
It should be noted that the triangle cannot be graphed because the coordinates are not numeric
