Step 1: Understand the characteristics of each word
Circle: A two-dimensional (2D) closed curve where all points are equidistant from the center.
Square: A 2D polygon with four equal sides and four right angles.
Triangle: A 2D polygon with three sides and three angles.
Cube: A three-dimensional (3D) solid with six square faces, twelve edges, and eight vertices.
Step 2: Identify the difference
Circle, Square, and Triangle are all flat 2D shapes, whereas Cube is a 3D solid figure.
Step 3: Conclude
Since Cube differs by being a 3D shape, it is the odd one out.
