Q:
# What is a seven-sided polygon called?

A:
### Quick Answer

**A seven-sided polygon is called a "heptagon."** "Hepta-" or "hept-" is a prefix from the Greek word meaning "seven." In addition to having seven sides, the heptagon also has seven angles where the sides meet.

The seven-sided figure is also known as a "septagon." However, this name is a combination of a Latin prefix, "septa-," with a Greek suffix, "-gon." Linguistics experts recommend use of "heptagon" as the name for this type of figure. In a regular heptagon, each of the interior angles is equal to 51.43 degrees. The word "heptagon" is rare in literature and use outside of mathematics.

Q:
## How do you draw a nonagon?

A:A nonagon is a nine-sided polygon in geometry. The Latin prefix "nonus" means "ninth." Like many polygons, nonagons can be regular or irregular. Regular nonagons have nine equal sides and nine interior angles equal to 140 degrees each. On the other hand, irregular nonagons have nine sides and angles that do not have to match, so they can be drawn in any way.

Q:
## What is a polygon called where all sides are congruent?

A:

Full Answer >**A polygon that has all sides congruent is called a "regular polygon."**Regular polygons must also have all angles congruent, which is a side effect of having congruent sides. For instance, a square must always have four 90-degree angles because of its four congruent sides.Filed Under:
