The trailing edge – The rear endpoint of the mean camber line is known as the trailing edge.

The chord line – The straight line joining the leading and trailing edges of the airfoil is known as the chord line.

Camber – The maximum distance between the chord line and the mean camber line and measured perpendicular to the chord line is known as Camber.

Thickness – The distance between the lower and the upper surfaces and also measured perpendicular to the chord line is known as thickness.
