How do you describe a pentagon?
In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A pentagon may be simple or self-intersecting. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.

Which is the best description of a pentagon?
Definition and Description of a Pentagon. 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…
What are the 5 sides and 5 angles of a pentagon?
Pentagon Definition A pentagon is a polygon with 5 sides and 5 angles. The word “pentagon” is made up of two words, namely Penta and Gonia, which means five angles. All the sides of a pentagon meet with each other end to end to form a shape.
Why do you draw lines through a pentagon?
That’s because when sides are equal distances from each other, their placement naturally creates equal-sized angles or corners. You can draw lines through a pentagon in five different places and divide it equally into two sections. These lines are called lines of symmetry. But not all pentagons are regular.
Is the Pentagon an irregular or regular polygon?
If all the sides are equal and all the angles are of equal measure, then it is a regular polygon. Otherwise, it is irregular. In the regular pentagon, the interior angle is 108°, and the exterior angle is of 72°. An equilateral pentagon has 5 equal sides.
