Naming 2D and 3D Shapes

Front

What is a cone?

Back

A cone is a three-dimensional geometric figure with a circular base that tapers smoothly from the base to a single point called the apex.

Front

What is a cylinder?

Back

A cylinder is a three-dimensional shape with two parallel circular bases connected by a curved surface at a fixed distance from the center.

Front

What is a rectangular prism?

Back

A rectangular prism is a three-dimensional shape with six rectangular faces, where opposite faces are equal in area.

Front

What is a triangular prism?

Back

A triangular prism is a three-dimensional shape with two triangular bases and three rectangular faces connecting the corresponding sides of the triangles.

Front

What is an equilateral triangle?

Back

An equilateral triangle is a triangle in which all three sides are of equal length and all three angles are equal, each measuring 60 degrees.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What is an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length and the angles opposite those sides are equal.

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths and all three angles are of different measures.

Front

What is a sphere?

Back

A sphere is a perfectly round three-dimensional shape where every point on the surface is equidistant from the center.

Front

What is a pyramid?

Back

A pyramid is a three-dimensional shape with a polygonal base and triangular faces that converge at a single point called the apex.
