Pythagoras Theorem is only taught at Sec 2. Not needed for this P5 question anyway.

Idea here is the usage of the two congruent triangles to compare the sides, and deduce 4 cm for one length and 3 cm for the other (P5 they use the word identical, since congruency and similarity is not formally taught yet , only at sec 2/3)
