FAQs on Shapes,Sides and Vertices Video Lecture - Class 1

1. What is the difference between a vertex and a side in geometry?
Ans. A vertex is the point where two or more lines or edges meet. In contrast, a side is a straight line that connects two vertices. Therefore, a side is a part of the perimeter of a shape, while a vertex is a point where two or more sides meet.
2. How many sides and vertices does a triangle have?
Ans. A triangle has three sides and three vertices. The sides are the straight lines that connect the three vertices, while the vertices are the points where two sides meet.
3. Can a shape have more vertices than sides?
Ans. No, it is impossible for a shape to have more vertices than sides. In a two-dimensional shape, each side connects two vertices, so the number of vertices cannot exceed the number of sides.
4. How many sides and vertices does a cube have?
Ans. A cube has six square faces, each with four sides, for a total of 24 sides. It also has eight vertices, where three edges meet.
5. What is the difference between a 2D shape and a 3D shape?
Ans. A 2D shape exists only in two dimensions, such as on a flat surface. It has length and width but no height or depth. In contrast, a 3D shape has length, width, and height, giving it depth and volume. It exists in three dimensions and can be represented in physical space.
