triangle

What?
Two lines can make an angle, but how can they make a triangle?
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°.
edge
I'm waiting for the answer
A triangle
vertex
When two line segments meet at a point
cross x
polygons
A closed plane figure formed by three or more line segments that do not cross is called a polygon. The line segments are known as the sides of the polygon, and the points where the sides meet are called vertices. Common examples of polygons include triangles, quadrilaterals, pentagons, and hexagons. Polygons can be classified as regular, with equal sides and angles, or irregular, with varying lengths and angles.
It is formed at a vertex when two line segments meet each other
A closed figure made from line segments that meet at their endpoints is known as a polygon. Polygons can have various numbers of sides, such as triangles (3 sides), quadrilaterals (4 sides), and so on. The points where the line segments meet are called vertices, and the segments themselves are referred to as edges or sides. Polygons can be classified as regular (with equal sides and angles) or irregular (with varying side lengths and angles).
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''
