Post your answers!

And also, what did your put for the last question of circil theorm question? I put 168 but people say its 138 degrees

 

[IGCSE O/L student]

i put similar!

 

[IGCSE O/L student]

Evem I put similar, actually one square was small and the other was big, therefore the lenghts would be differentt actually I was never taught of that rule

one side of one triangle ws equal 2 da side of da other triangle, n so ws another side.
