Identify shapes traced from solids

Key notes :-

🧊 1. What Are Solid Shapes?

  • Solid shapes are 3D shapes.
  • They have faces, edges, and vertices.
  • Examples: Cube, Cylinder, Cone, Sphere

✏️ 2. What Does “Traced from Solids” Mean?

  • When we press or roll a solid shape on paper, it leaves a flat shape.
  • This flat shape is what we trace or see on paper.

🟢 4. Easy Examples

  • Press a cube = Square
  • Roll a cylinder = Rectangle
  • Press the base of a cone = Circle
  • Roll a sphere = Circle

Learn with an example

🖋️Can you make a circle by tracing this shape?

  • yes
  • no

The shape is a cone.

The flat part of a cone is a circle. The rest of the surface is curved. Here is the flat part.

  • So, the correct answer is yes. You can make a circle by tracing a cone.

🖋️Can you make a square by tracing this shape?

  • yes
  • no

The shape is a cube.

All flat parts of a cube are squares. Here is one flat part.

  • So, the correct answer is yes.You can make a square by tracing a cube.

🖋️Can you make a circle by tracing this shape?

  • yes
  • no

The shape is a cylinder.

Both flat parts of a cylinder are circles. The rest of the cylinder is curved. Here is one flat part.

  • So, the correct answer is yes. You can make a circle by tracing a cylinder.
