Test: 3D Shapes- 1 - Class 4 MCQ

A cone is a three-dimensional solid that has a circular base joined to a single point (called the vertex) by a curved side. You could also think of a cone as a “circular pyramid”.

Both a cylinder and a sphere will roll since they both contain a curved face. Spheres will roll in every direction, however, the cylinder will only roll in one direction when placed on its side.

A square box is a solid figure in which all six faces are rectangles with three pairs of parallel congruent opposite faces.

An edge is the line segment where two faces meet. You can see by looking at this cube that the faces intersect in a line. Many solid figures have more than one edge. A vertex is a point where several planes meet in a point.

In geometry, a closed shape can be defined as a enclosed shape or figure whose line segments and/or curves are connected or meet. They start and end at the same point.

For example circle. 

A cylinder is a three dimensional object with a circular base and straight parallel sides that looks similar to a can of coke.

A rectangle has 2 pairs of parallel sides, 2 pairs of equal sides and 4 right angles. 

A triangle is a three-sided polygon (2d Shape) which has three edges and three vertices. The sum of all the three angles of a triangle is equal to 180°.

Three-dimensional geomentric figures are called solids. 

A cylinder is a solid figure with two parallel congruent circular bases.
