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:
- Break Down the Figure: Divide the figure into smaller, simpler parts. Look for patterns and repetitions in these parts.
- 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.
- Identify Overlapping Triangles: Pay attention to triangles that share sides or vertices. These overlapping triangles might be counted more than once, so be cautious.
- Count Larger Triangles: Move on to counting larger triangles that are formed by combining the smaller sections you counted in the previous steps.
- 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.
- 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.
- 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.
- 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.
- 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.
