Question

| Q11 Find the length of the equal sides of a

right-angled isosceles triangle if the
length of its hypotenuse is 40cm.

Answer 1

If you know the hypotenuse length of a 45 45 90 triangle, the length of the leg = hypotenuse * (1 / (sq root 2))

leg length = 40 cm * (1 / 1.4142135623731 )

leg length = 40 cm * 0.7071067811865

leg length = 28.2842712474619 cm
