## Why do we need to study polygons?

Polygons are an important part in the education of students as they teach them how to make patterns, tessellations, how to use poly- gons to make other shapes, build on polygons to form 3D shapes and about symmetry.

## Can a Pentagon be any shape?

Pentagons can be regular or irregular and convex or concave. A regular pentagon is one with all equal sides and angles. Its interior angles are 108 degrees and its exterior angles are 72 degrees. An irregular pentagon is a shape that does not have equal sides and/or angles and therefore do not have specified angles.

The name nonagon is a prefix hybrid formation, from Latin (nonus, “ninth” + gonon), used equivalently, attested already in the 16th century in French nonogone and in English from the 17th century.

## Does a Pentagon have a 90 degree angle?

We may be tripped up on the fact if a ‘regular’ pentagon is present there is zero 90% angles present. 108 * 5 interior angles = 540 of the pentagon. Rest assured the ‘irregular’ pentagons can have 1–3 90% right angles.

## Which has more sides a hexagon or a pentagon?

A hexagon has more sides than a pentagon. A hexagon is a polygon that has six sides and a pentagon is a polygon that has five sides.

decagonIn geometry, a decagon (from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°.

## Can a Pentagon have four right angles?

A quadrilateral can have four right angles. Sum of Interior Angles = 540′. Four right angles would leave 180′, which is impossible. So a pentagon has a maximum of three right angles, as shown.
