How to count number of Triangles ?

This video explains it in very easy way.

Counting the number of triangles in a complex figure can be challenging, but there are some tricks you can use to make the process easier. Here’s a step-by-step approach:

  1. Break Down the Figure: Divide the figure into smaller, simpler parts. Look for patterns and repetitions in these parts.
  2. Count the Triangles in Each Part:
    • Start by counting the triangles in the smallest sections of the figure.
    • Identify equilateral triangles (all sides and angles are equal) and other types of triangles.
  3. Identify Overlapping Triangles: Pay attention to triangles that share sides or vertices. These overlapping triangles might be counted more than once, so be cautious.
  4. Count Larger Triangles: Move on to counting larger triangles that are formed by combining the smaller sections you counted in the previous steps.
  5. Check Your Count: Once you’ve counted all the triangles in each part and combined them to count the larger triangles, double-check to ensure you haven’t missed any or counted any twice.
  6. Use Visualization Techniques:
    • Look for patterns in the arrangement of triangles. Sometimes, they form rows or columns that are easy to count.
    • Imagine lines connecting the vertices of triangles to help you visualize their presence.
  7. Practice and Patience:
    • Counting triangles accurately in complex figures can take practice. Don’t get discouraged if it takes a bit of time to get the hang of it.
  8. Use Colors or Marking:
    • If it helps, use different colors or marks to identify the triangles as you count them. This can help you keep track of which ones you’ve already counted.
  9. Start from Different Points:
    • Sometimes, starting from different points in the figure can lead to a clearer counting process.

Remember that these tricks might work better for some figures than others, and there might be cases where counting triangles remains a bit challenging. With practice, your counting skills will improve, and you’ll become more efficient at identifying triangles in complex figures.
