A, material preparation:
Cardboard or cardboard: used to make the main body of the model.
Scissors: used to cut paper.
Glue: a tool for bonding model parts.
Ruler: used for measurement and planning.
Second, the production steps:
1. Prepare triangle template:
Draw an equilateral triangle on the cardboard with a ruler and pencil, and each side is equal in length.
Using this triangle as a template, draw at least three identical triangles, which will become the sides of a triangular prism.
2. Making triangular prism side:
Cut three identical triangles.
Arrange them in turn to ensure that their edges are aligned. Then glue them together to form a triangular column.
3, manufacturing the bottom surface and the top surface of the triangular prism;
Draw a triangle with the same length as the bottom of the triangular column as the bottom surface.
Use triangles of the same size or triangles with shorter sides to make the top surface.
4. Assemble bottom surface, side surface and top surface:
Use glue to connect the bottom and top surfaces with the bottom and top of the triangular column.
Make sure the parts are aligned and let them dry completely after bonding.
Third, tips and techniques:
Accuracy: Try to keep the sides and angles of the triangle consistent to ensure the stability and symmetry of the triangular prism.
Experimental diversity: Try to use triangles of different sizes, or add more triangles to the sides to create triangular prisms of different shapes.
Making a three-dimensional model of triangular prism is a simple and interesting manual project, which can exercise your hands-on ability and spatial imagination. According to your own ideas and creativity, you can try to make triangular prism models with different specifications, sizes and shapes.
