**Solution:**

**Steps :**

- Initial draw square pyramid as (T.V.)
_{1}Such that one side is parallel to*xy*, a project is a Front view as (F.V.)_{1} - Draw (F.V.)
_{2}Such that one of the triangular faces says*o*‘*b*‘*c*‘ lies on H.P. project its Top view with the help of (T.V.)_{1}and (F.V.)_{2}as (T.V.)_{2}. - Inclined the axis of pyramid 45
^{0}to*xy*. This Final T.V. with the help of final T.V. and (F.V.)_{2}draw final F.V.
