Question 397669
It says a triangle is 18 inches wide and 3 inches tall.
 if it is reduced to a width of 6 inches then how tall will it be?
:
If the triangles are similar (same angles) the relationship between the sides
remains the same; let h = the height of the reduced triangle
{{{18/3}}} = {{{6/h}}}
cross multiply
18h = 18
h = 1 inch tall
