let's consider (0,1) and (0,6) to be the base,
the the base is 5 units.
let the height be h
giving us a nice isosceles triangle
(1/2)(5)h = 10
5h = 20
h = 4
so a possible third point is (4, 3.5)
As a matter of fact, we could now take any point along the vertical line x = 4
Since x = 4 is parallel to the y-axis, the distance between them is always 4 and the base of our triangle is always 5, giving us an area of
(1/2)(4)(5) = 10
A third point looks like (4, k), where k is any real number.
Two vertices of a right triangle are (0,1) and (0,6). The area of the triangle is 10 square units. Which point could be the third vertex of the triangle?

Forgot to mention that we could also have placed out third point on the left side of the y-axis,
e.g. (-4,8) would work
