None, since there are no right angles in a pentagon. The angles are 360/5 = 72o
Two lines that intersect at a right angle are perpendicular.
A pentagon has no parallel lines.
A pentagon has five sides.
There are 5 lines of symmetry in a regular pentagon but a less amount in a irregular Pentagon
a pentagon has 10 lines of symmetry
A regular pentagon has no parallel lines.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
A regular pentagon has 5 lines of symmetry, running from each vertex to the midpoint of the opposite side. These lines are not to be confused with the five lines it takes to draw a pentagon. Every regular polygon has as many lines of symmetry as there are lines in the polygon.An irregular pentagon may have none or 1 line of symmetry.
A regular pentagon has 10 lines of symmetry. This counts the five points of the pentagon as well as the midpoints of each side.
any regular pentagon has five lines of symmetry.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.
five, if it's a regular pentagon.
