Question

Using Pythagoras' theorem, calculate the

length of the hypotenuse in this right-
angled triangle.
Give your answer in centimetres (cm) to
1 d.p.
2 cm
1.5 cm

Answer 1

Hypotneuse is 2.5 cm.

Explanation:

Hyp^2=Sum of the squares of the other two sides
a^2 = b^2+ c^2
hyp^2 = (2)^2 + (1.5)

hyp^2 = 4 + 2.25

hyp^2=6.25

Apply sq. root on both sides

hyp = 2.5 cm
