The diagram below shows a right pyramid VABCD with V as the vertex. The base of the pyramid is rectangle ABCD, with AB = 4 cm and BC= 3 cm. The
height of the pyramid is 6cm.
(a) Calculate the
(i) Length of the projection of VA on the base
(ii) Angle between the face VAB and the base
(b) P is the mid- point of VC and Q is the mid – point of VD.Find the angle between the planes VAB and the plane ABPQ
