i was so lost in class and after watching this i have gained confidence in this topic thank you so much Sir.

Triangle AED had a parallel base with the line inside it so why did you rule out proportionality in that situation?

[yuvnaramsarup]

couldnt it also be similarity for angle angle side since AC=DE ?

You're a wonderful teacher.. Thank you so much for making my life easier 😘😘😭you're the best ⚡🥺

Hi ...so why didn't we use proportionality ...the first triangle u indicated ( green) does have that parallel line in the triangle

[killab]

Sir is it mandatory to include the reason "sum of angles in a triangle" when you're at this step 2:55 ?? because so far i watched your similarity videos and I find it is still the same reason when your at the same step

Isnt ACB = E also ext angle of cyclic quad ?

[xiyimosono]

there is proportionality in triangle ADE kev

[Nkosana]

Is it possible to prove the similirity of triangles using 2 angles and a side instead of angles only?

[knightinshiningarmour-rw]

sir I don't agree with the exterior angle of a quad reason cos that line doesn't look like it's coming from the quad😭😭😭
