Question

Is it possible for a pentagon to have no acute angles?

Answer 1

A pentagon does not have have an any acute angles.

Answer 2

All angles are obtuse.

Answer 3

@zordoloom I wouldn't be too sure of that...

Answer 4

The interior angles of a regular or irregular pentagon always add up to 540 degrees.
So for a regular pentagon, one angle would be 108 degrees, no acute angles.

As for an irregular polygon, as long as the interior angles add up to 540 degrees, there is no reason it cannot have acute angles.

Answer 5

As you can see, all angles are greater than 0 in a regular pentagon.

Answer 6

thanks :)

Answer 7

Meh.... I meant irregular pentagon... My apologies.
