Rectangle with Triangular Extensions - Geometric Net Diagram #3087160 (License: Personal Use)

This schematic illustrates a 2D net composed of a central rectangle and two identical isosceles triangles attached to opposite sides, connected via dashed lines indicating fold lines. The configuration is standard for constructing a triangular prism in solid geometry, where the rectangle forms the lateral surface and the triangles serve as the bases. The dashed interior lines denote edges that become internal when folded.

Used in math education resources, geometry textbooks, or interactive learning platforms to teach 3D shape construction from 2D nets; matches user intent for visualizing prism assembly or preparing printable craft templates.
