Prove that a line that divides two sides of a triangle proportionally is parallel to the third side. Be sure to create and name the appropriate geometric figures.
|dw:1397000487880:dw| for now lets pretend this is your drawing
lol ok well its easier if you look at it from a different perspective so i made a rectangle with a triangle divided into 3rds
sorry it was way less complicated in my head
is this for your geometry class?
lol i have not learned this yet
@iambatman could you help us out
what im thinking is that if shapes are proportional all the dimensions are proportional as well right?
RANGA THANK GOD CAN YOU HELP ME

If you prove triangles ADE and ABC are similar, then you can prove DE is parallel to BC.
wow our drawings were off lol i actually did go over this in october
yeah.. Thats what I'm trying to do.. I dont want the answer I wanna try on my own.. well with help. so I have to prove similar angles?
yes
so angle b= angle b by reflective property of equality?
If you prove triangles ADE and ABC are similar, then, angle ADE = angle ABC and angle AED = angle ACB. They are corresponding angles and therefore DE is parallel to BC.
sorry what?
