The name of a regular polygon with five equal sides and five equal angles is a pentagon. Each of the internal angles is equal to 108 degrees.
A plane shape with five sides of equal length, and five equal angles: each of 108 degrees.
It is not possible to have five perpendicular sides; four or eight, but not five. A shape with five equal sides is a pentagon.
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A pentagon has five sides and five angles, the only 2-D shape with these characteristics.
A regular pentagon.
octagon
The Pentagon has the geometric shape of a pentagon (It is a polygon with five interior angles and five equal sides).
A regular pentagon
A shape with 5 sides and 5 angles is a pentagon.
The name of a regular polygon with five equal sides and five equal angles is a pentagon. Each of the internal angles is equal to 108 degrees.
A plane shape with five sides of equal length, and five equal angles: each of 108 degrees.
A regular pentagon. A regular pentagon has five sides of equal length and its five angles are also equal. The term regular implies the notion of equal sides and equal angles.
Pentagon
It depends! If all its sides and angles are the same then it is a regular pentagon, however, if it's a five sided shape (5 straight sides that join to make a single shape), but it's sides or angles are not equal then it is an irregular pentagon.
A shape with five angles and five sides that do not all measure the same is an irregular pentagon. A regular pentagon has all five sides and angles the same size.
It is not possible to have five perpendicular sides; four or eight, but not five. A shape with five equal sides is a pentagon.
