1.	The side of a square is 6 cm, what would be the square of it’s diagonal’s length?(a) √72(b) 36(c) √36(d) 72This question was addressed to me in my homework.This intriguing question originated from Quadrilaterals topic in section Quadrilaterals of Mathematics – Class 8
Answer» Right answer is (d) 72 To explain: As the diagonals of a square are perpendicular bisectors of each other, the form a right ANGLES triangle. Here to find the length of the diagonal could be FOUND by using Pythagoras THEOREM. ∴ By Using Pythagoras Theorem we get, ∴ (6)^2 + (6)^2 = x^2 ∴ 36+36=x^2 ∴ 72=x^2
