if you join all the vertices of a heptagon how many quadrilaterals will you get?

  • math -

    A Heptagon has 7 sides, and, therefore,
    7 vertices. There are 4 vertices per Quadralateral.

    7/4 = 1 3/4 Quadralateral.

  • math -

    Wow that answer is so wrong. There are 7 vertices, and each quadrilateral does have 4. That much is true. But this problem requires a bit deeper thinking. You need to determine how many quads. each vertex will create. The answer is 5. Multiply that number by the # of vertices (7), and you will get the ACTUAL answer...35. You can do this by drawing it out for one vertex and then multiplying by 7.
