The coordinate of C is (a,0) and the coordinate of M is (a/2,0)
The triangle is said to be a right isosceles triangle.
This means that the coordinates of C are: the y coordinate of B, and the x coordinate of A.
So, we have:
C = (a,0)
The midpoint M is then calculated as:
[tex]M = \frac{A + C}2[/tex]
This gives
[tex]M = \frac{(0,0) + (a,0)}2[/tex]
Add the corresponding coordinates
[tex]M = \frac{(0 + a,0 + 0)}2[/tex]
[tex]M = \frac{(a,0)}2[/tex]
Divide
[tex]M = (\frac a2,0)[/tex]
Hence, the coordinate of C is (a,0) and the coordinate of M is (a/2,0)
