a line of symmetry is the middle of a shape that is the same on both sides
The line of symmetry in a shape is found be looking at the sides of the shape. If you see that two sides look the same, try to draw a straight line through them. The line of symmetry acts like the dotted line in which you fold you paper. If you can fold the shape across the line of symmetry, and the shape is exactly the same on both sides then you have found A line of symmetry.
Symmetry is dividing a shape or figure in a certain way so that both sides are the same. Usually the line of symmetry, the line separating the shape, is a straight line.
A plane shape with five sides of equal length, and five equal angles: each of 108 degrees.
It has four sides.
a quateratural is any shape that has 4 sides
It's just when you rotate a shape. Each time you rotate it, and it looks exactly like the shape you had before you started rotating, is one line of rotational symmetry.
It can look like a four-sided shape with five sides or a five-sided shape with four sides. The term is self-contradictory and so such a shape cannot exist!
A heptagon is a 2-dimensional shape that has 7 sides.
A line of symmetry can be thought of as the line where you could cut a shape (or a line or any object) and it would look the exact same on both sides. An example of a shape with exactly two lines of symmetry would be a rectangle. A square also has at least two lines of symmetry, but it actually has four total.
It is a shape that has 8 sides but does not look like a regular octagon. As long as it has 8 sides it is an irregular octagon.
