b)

1.3)

a)

b)

1.4)

 Pythagoras theorem for right angled triangles states that the square of hypotenuse is equal to the sum of the squares of the other two sides.

Hypotenuse²  = Perpendicular² + Base²

`1.5)

pythogreous theorem can be used in archiecture and construction to determine the length of a diagonal connecting two sides.

for example ,it can be used to determine the length of a ladder to be used in the building.
