Yes.
A circle is not formed from line segments.
If it has 3 or more line segments then it is a polygon
a pentagon has five sides and five angles
A polygon, but only if all the line segments are coplanar.
6 hex=6
When two line segments meet at a point
what of a triangle has three line segments that intersect only at their endpoints
A circle is not formed from line segments.
An angle comprises two straight line segments or rays together with the point at which they meet.
Perpendicular line segments are line segments that intersect and make 90 degree angles.
Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.
You cannot have a shape without any line segments.
If it has 3 or more line segments then it is a polygon
A simple closed figure formed by line segments joined together. The point where the sides meet is called the vertex (vertices, plural). A regular polygon is formed when all the sides are equal. Polygons are named by the number of sides and angles they contain.
straight line,triangle,rays angles
a pentagon has five sides and five angles
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
