Answer:
The answer is 5 triangles.
Step-by-step explanation:
A heptagon is a seven sided polygon.
So, the number of triangles that can be drawn from 1 vertex in any polygon with n sides, is given by :
.
Therefore, in a heptagon, we can draw
triangles.
The sum of the interior angles of a heptagon is 900 degrees. We can check this by taking the total interior angle sum of 5 triangles.
Sum of internal angle of triangles is = 180 degrees.
So, sum of 5 triangles will be =
degrees.
This proves, a heptagon can have 5 triangles.
