11. The slope of a line is 1/5. Label the two right triangles with dimensions that would allow the
triangles to lie on the same line.

Step-by-step explanation:

If the slope is 1/5, we can interpret this as rise/run = 1/5.  We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:

hypo = +sqrt( 1^2 + 5^2)

In this case we dilate the triangle defined by the slope 1/5:  

2/10,        1/10/(1/2),           10/50,        etc.,       all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).
