Are all 3D shapes made from 2d shapes?
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
What is the relationship between 2 d and 3 d shapes?
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width
How many 2 D shapes are there?
34
Are isosceles triangles 3-d shapes?
No because isosceles triangles are 2 dimensional shapes.
How many triangular prism are there in faces?
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
Are all 3D shapes made from 2d shapes?
3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
What is the difference between 2-d shapes and 1-d shapes?
1
List a few 3-d shapes?
Sphere, cuboid, tetrahedron.
What is the relationship between 2 d and 3 d shapes?
3 dimensional shapes have breadth, width and depth whereas 2 dimensional shapes have only breadth and width
How many 2 D shapes are there?
34
Do 2 d shapes have flat faces?
yes
Are isosceles triangles 3-d shapes?
No because isosceles triangles are 2 dimensional shapes.
How many triangular prism are there in faces?
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
Can 2 d shapes have faces?
No, they have only one face.
What is the definition of 2-D shapes?
2d shape is a dimension
How many triangular faces are in triangular prism?
There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.
How do shapes get there name'?
Polygonal (2-d) shapes get their (not there) names from the number of sides; polyhedra (3-d) shapes get their names from the number of faces.The names of other shapes: circles, ellipses, torus, cardioid etc have different origins.
