**P****R****O****J****E****C****TI****O****N OF PLANES**

A Plane is a two dimensional entity having only length and breadth with negligible thickness which is considered as zero.

**T****YPES OF PLANES**

Planes may be divided as two main types. They are

(I) Perpendicular Planes

(II) Oblique Planes.

**P****e****r****p****e****nd****icular Planes**

Planes which are perpendicular to any one of the principal planes of projection are called as perpendicular planes. These planes may be inclined or parallel to the other principal plane.

**V****arious positions of perpendicular planes**

**(****a) Planes perpendicular to V.P. And Parallel to H.P.**

Consider a plane perpendicular to V.P. And Parallel to H.P. The top view reveals the true shape of the plane

The front view is a line parallel to xy line.

**(****b****) Planes perpendicular to H.P. And Parallel to V.P.**

Consider a plane perpendicular to H.P. And Parallel to V.P. The front view shows the exact shape and size of the plane. The top view is a line parallel to xy line

**© Plane perpendicular to both H.P. And V.P.**

Consider a plane in space which is perpendicular to both the H.P & V.P.

Both the front view and top view of the plane appear as a straight lines on a single projector.

**(****d****) Plane perpendicular to V.P. And inclined to H.P.**

Consider a plane perpendicular to V.P. And inclined at an angle to the H.P. The top view is shorter than its ture size.

The front view is a line inclined at an angle to xy line .

**(****e****) Plane perpendicular to H.P. And inclined to V.P.**

Consider a plane perpendicular to the H.P. And inclined at an angle to the V.P. The front view is shorter than its true size.

The top view is a line inclined at an angle to xy line.
