Q.1 Here you find four nets (Fig 15.10). There are two correct nets among them to make a tetrahedron. See if you can work out which nets will make a tetrahedron.
A tetrahedron is a three-dimensional shape with four triangular faces. It has four vertices and six edges.
A net of a tetrahedron consists of four triangles arranged in such a way that they can be folded to form the tetrahedron.
Out of these four nets, we can make a tetrahedron with net (i) and (iii)
