Learn how to use the proportionality theorem in Grade 12 maths.

For all those who's getting 4/3 as an answer Ive also made the same mistake. Remember because DE/AD = BC/AC. This means your answer will be 2x/5x.

Because CB is equal to 2x
And AC = 2x + 3x
(because CB + AB = AC)

And if you were to further calculate you'd get Kevins answer which is 4/5

Greetings sir, it's me again... Id like ask bout the answer for GF, i got 4 over 3 instead of 4 over 5...why is that tho

Hi Kevin, quick Q.
GF= 4/5

But it's supposed to have units. That is GF= 4/5 cm.

Am I right?

Hey sir lots of confusion is made here the 2cm is mostly placed on the FA side and most of us believe that 2cm is of FA but when you check the statement it’s tells the right thing 😂 that GA is cm

sir i was penalized for not drawing my construction lines and my whole proportionality question was not marked at all, how do i construct my lines on my answer booklet

Prop theorem seems to be quite a problem. I mean the reason.
