The perimeter
out line
It's a "LINE" or a "CURVE"
Polygon
The perimeter is both on the outside and the inside of a shape, as it is basically the outside wall/border of a shape and can therefore be viewed from the outside or the inside.
You cannot have a shape without any line segments.
out line
It is called a area.
It is a tangent line
its called a heptagon
Is this a quiz? If so I think the answer is line of symmetry?
Find the length of each line you use to draw the outside of the shape, then add them all up.
The line that separates a shape into two matching halves is called the line of symmetry. When a shape is folded along this line, both halves mirror each other perfectly. In geometric figures, this line can be vertical, horizontal, or diagonal, depending on the shape's orientation.
