Personally for proving questions especially trigo, i reckon u memorise all of the formulas, esp double angle and half angle.

also, for other types of proving qn like prove d = 1/2 in an a.p, u can always go back to your basics, which is U1 + d = U2.

but, i would say that as long as u practice a lot of questions u should be able to recognise how to prove the questions

Identify which triangles are congruent, and explain your answer.

Paha777 [63]

I believe that A and D would be the correct answer. Because both are 30,60,90 triangles and would be congruent. The other 2 triangles only have 1 angle and their side measures are at two different places meaning they cannot be congruent.
