There are 21 vertices in seven triangles.
10 triangles....
3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.
There are 5 triangles in an heptagon
All triangles have 3 sides and 3 vertices.
There are 21 vertices in seven triangles.
All triangles have 3 vertices

13 triangles will be formed
a tetrahedron is made of four triangles and has 4 vertices.
All triangles have three vertices.
There are 5 triangles in an heptagon
You can fit 7 regular/equilateral triangles inside a Heptagon since a Heptagon has got 7 sides and vertices.
All triangles have exactly three vertices.
