According to the triangle proportionality theorem, which proportion is correct?

question 1 options:

am/mn = mb/bc
am/nc=an/mb
mb/am=nc/an
am/mn= an/mn

According to triangle proportionality theorem:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

And in the given triangle, MN parallel to BC, So MN divided the two sides in proportion, that is

Correct option is the third option .

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
