📚 Topic Summary

Composing shapes means putting two or more shapes together to create a new shape. Think of it like building blocks! You can use squares, triangles, rectangles, and other shapes to form bigger, more complex figures. By understanding how shapes fit together, you can solve geometry problems and create amazing designs!

🧩 Part A: Vocabulary

Match the term with its definition:

  1. Term: Quadrilateral
  2. Term: Triangle
  3. Term: Pentagon
  4. Term: Hexagon
  5. Term: Compose
  1. Definition: A polygon with six sides.
  2. Definition: A polygon with three sides.
  3. Definition: To put shapes together to form a new shape.
  4. Definition: A polygon with five sides.
  5. Definition: A polygon with four sides.

Instructions: Write the number of the term next to the corresponding definition.

✏️ Part B: Fill in the Blanks

Read the paragraph and fill in the missing words.

When we _______ shapes, we are creating a new shape by joining two or more shapes. For example, you can put two _______ together to make a _______. Similarly, two triangles can form a _______. Understanding how shapes _______ together helps with geometry and problem-solving!

🤔 Part C: Critical Thinking

Imagine you have two identical right triangles. What different shapes can you make by composing them? Draw the shapes you can create and describe them.
