Naresh is a visually challenged student of his class. He identifies and count edges, corners and faces of various three dimensional (3D) shapes by touching them. How many edges, corners and faces will he identify in a triangular prism?

Naresh is a visually challenged student of his class. He identifies and count edges, corners and faces of various three dimensional (3D) shapes by touching them. How many edges, corners and faces will he identify in a triangular prism? Correct Answer Edges = 9, Corners = 6, Faces = 5

Visually challenged students are born with visual impairment or become visually impaired later due to illness, malnutrition, or an accident. They can be partially or fully blind. Suitable teaching strategies should be used to cater needs of these children.

Key PointsA prism with 2 triangular bases and 3 rectangular sides is known as a triangular prism.

  • The edges in the vertices of the bases are connected with 3 rectangular sides.Additional Information

    • A face is a flat surface.
    • An edge is where two faces meet.
    • A vertex is a corner where edges meet. The plural is vertices.
