Its shadow. Except that it does not have the same shape. A plane has a 3-dimensional shape, a shadow does not.
No, the plane would weigh the same.
Any plane shape can have the same perimeter as any other plane shape.
yes. because you didn't add anything to it or take anything away from it. so it's just a different size.
Any plane shape can have the same area as any other plane shape if the dimensions are carefully selected
A translation moves every point on a shape in the same distance and in the same direction on the Cartesian plane
Anything that is coplanar.
Coplanar means "on the same plane". A plane can be a figure or shape like a rectangle. Coplanar points means points that belong on the same plane.
why does son have not same gravity on planet? why does plane not move in round shape when the gravity is same?
A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
The shape of a circle is round. Circles are plane shapes that have all points that are the same distance from the center.
anything that has the same dimensions and shape
No. A 2d shape is a plane area, which may be regarded as a face, which is bounded by a side or sides.
