Puzzle: Solve the addition puzzle and review closed shapes

What is the final answer to the addition puzzle?

1 + 2 + 3 + 4 + 5 = ?

How can you identify closed shapes with only 3 vertices?

Circle the closed shapes with only 3 vertices.

Answer:

The final answer to the addition puzzle is 15.

Explanation:

To solve the addition puzzle, you simply need to add up the numbers given: 1 + 2 + 3 + 4 + 5 = 15. This is a basic arithmetic calculation that requires adding each number consecutively.

To identify closed shapes with only 3 vertices, you need to circle the triangles. A triangle is a closed shape with three vertices or corners.

Addition Puzzle Solution

The addition puzzle is solved by adding each number provided: 1 + 2 + 3 + 4 + 5 = 15. This is a simple arithmetic calculation that helps practice basic math skills.

Identifying Closed Shapes

Circle the shapes with only 3 vertices to identify triangles. A triangle is a closed shape made up of three line segments, with three angles. It is the simplest polygon and a fundamental geometric concept.

Recognizing and identifying triangles helps develop spatial reasoning and critical thinking abilities. It is important for understanding geometric concepts and shapes in mathematics.
