When a regular polygon with n sides is decomposed into triangles using the same vertex, how many triangles are formed? (1 point)
The number of triangles formed when a regular polygon with n sides is decomposed using the same vertex can be calculated using the formula:
Number of triangles = n - 2
So, the answer is n - 2 triangles.
When a regular polygon with "n" sides is decomposed into triangles using the same vertex, the number of triangles formed can be calculated using the formula:
Number of Triangles = n - 2
So, the number of triangles formed is equal to "n" minus 2.
To find the number of triangles formed when a regular polygon with n sides is decomposed using the same vertex, we can follow these steps:
1. Recall that a regular polygon has all sides and angles equal.
2. Each triangle is formed by connecting one of the vertices with the central vertex.
3. So, for each side of the regular polygon, a unique triangle is formed.
4. Since a regular polygon has n sides, there will be n triangles formed by connecting each side to the central vertex.
5. Therefore, the number of triangles formed when a regular polygon with n sides is decomposed using the same vertex is equal to n.
