Printable worksheets: sides and vertices of shapes (2nd grade)

📐 Topic Summary

In geometry, shapes are all around us! Each shape has sides, which are the straight lines that make up the shape. The point where two sides meet is called a vertex (or vertices if there are more than one). Learning about sides and vertices helps us understand and describe different shapes like squares, triangles, and rectangles.

For example, a triangle has 3 sides and 3 vertices. A square has 4 sides and 4 vertices. Knowing this helps us tell shapes apart! Let's get started on the worksheet!

📖 Part A: Vocabulary

Match the word with its definition:

1. 📏 Side
2. 📌 Vertex
3. ⬛ Square
4. 🔺 Triangle
5. 🔲 Rectangle

Definitions:

1. A shape with four equal sides and four right angles.
2. A shape with three sides and three vertices.
3. A straight line that forms part of a shape.
4. A point where two or more lines meet.
5. A shape with four sides and four right angles, where opposite sides are equal.

✍️ Part B: Fill in the Blanks

Read the paragraph and fill in the missing words.

A __________ has three sides and three __________. A __________ has four sides and four vertices, where all sides are equal. A rectangle also has four sides and four vertices, but only opposite sides are __________.

🤔 Part C: Critical Thinking

Imagine you are building a robot. You want the robot to have a body shaped like a polygon (a shape with straight sides). What shape would you choose for the robot's body and why?
