Question

What is the sum of the measures of the interior angles of a heptagon

Answer 1

A heptagon has 7 sides and can be divided into 5 triangles. How many degrees in the angles of 1 triangle?

Answer 2

Well don't all of the interior angles of a polygon add up to 360?

Answer 3

@Mertsj

Answer 4

That would be exterior

Answer 5

Oh, right. My bad. Could we use the interior angles equation
\[\frac{ (n-2) \times 180}{ n }\]
where n is the amount of sides? All he/she would have to do is know how many sides a heptagon has?

Answer 6

Do you agree that all of the angles of those triangles make the 7 angles of the heptagon?
