slopes of the corresponding sides of triangle B. How do the lengths of their bases compare?

A. The base of A is quadruple that of B. The base of A is double that of B.

C. The base of A is half that of B.

D. The base of A is one quarter that of B.

I thought it would be B, but its A, how?

**Reiny**, Monday, January 17, 2011 at 10:01pmlet the height of both triangles be h

let the base of triangle A be 2x

let the base of triangle B be 2y

slope of side of A = h/x

slope of side of B = h/x

but h/x = 2 (h/y

1/x = 2/y

y = 2x

or

x = (1/2)y ----> base of A is half that of B
