Step-by-step examples of drawing triangular prism nets with solutions

📚 Quick Study Guide

• 📐 A triangular prism has 5 faces: 2 triangles and 3 rectangles.
• 📏 A net is a 2D shape that can be folded to form a 3D shape.
• ✏️ To draw a net, visualize unfolding the prism. Think about which faces are connected.
• ➗ The rectangular faces share sides with the triangular faces.
• ✨ Ensure all faces are connected along an edge in your net.
