Question

State if the three sies lengths form a right triangle ; 10 cm , 49.5 cm , 50.5 cm

Answer 1

Well, 10<49.5+50.5, 49.5<10+50.5 and 50.5<10+49.5
Because these conditions are obeyed, you have a triangle.
A right triangle requires that
`50.5^2=10^2+49.5^2 \\ 2550.25=100+2450.25`
which is true. So, the triangle has a right angle.
