Calculate the length of the hypotenuse of a right-angled triangle when the other two sides measure 6cm and 9cm.

Pythagoras theorem which applies to right angled triangles is summarised by the following formula: c2= a2 + b2 where 'c' is the hypotenuse of the triangle, whilst 'a' and 'b' are the two sides that connect to form the right angle. (ideally would have diagram below).Inputting the values from the above question into this formula: c2= 62 + 92 -> c2= 36 + 81 -> c2= 117 -> c=square root of 117
