polygons
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
They are equal line segments that meet at an angle of 135°.
I'm waiting for the answer
edge
A triangle
vertex
When two line segments meet at a point
cross x
polygons
It is formed at a vertex when two line segments meet each other
They are perpendicular line segments
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.
there where a polygon meet that 2 segments is called ''vertex''
Line
The definition of perpendicular lines also defines the angles -- perpendicular lines are two lines (or line segments) that meet at a 90 degree angle.
The points where the line segments that form a polygon meet (i.e., the corners) are called the vertices of the polygon. The singular form is vertex.
