yes they can. They can be the bottom+top or the left+right.
There are actually several lines of symmetry for a regular octagon. An irregular octagon could have fewer.
Technically, a square is a rectangle with four lines of symmetry. A non-square rectangle has exactly two lines of symmetry: the vertical and the horizontal.
Rectangles and Rhombuses (if they are not also a square. Squares have 4 lines of symmetry.)
If it is irregular most likely not. I know it is possible to have 2 lines of symmetry but I'm not so sure about 3 lines. Maybe you can figure it out by drawing it for yourself.
H
A regular octogon has 8 lines of symmetry. * * * * * An irregular octagon can have 0, 2 or 4.
An octagon is a 2-dimensional figure, not a line of symmetry. However, it has several lines of symmetry.
A regular octagon has 8 lines of symmetry and one center point of symmetry An octagon can also have fewer lines of symmetry: 0, 2 or 4 .
A rectangle has exactly 2 lines of symmetry
The Oct- prefix means 8, so an octagon has 8 sides and 8 angles A regular octagon has 8 liens of symmetry; irregular octagons can have 0, 1, 2 or 4 lines of symmetry
quadrangle with exactly 2 lines of summetry
0, 1, 2, 4 or 8.
There are actually several lines of symmetry for a regular octagon. An irregular octagon could have fewer.
Technically, a square is a rectangle with four lines of symmetry. A non-square rectangle has exactly two lines of symmetry: the vertical and the horizontal.
There are two quadrilaterals with 2 lines of symmetry. A rhombus and a rectangle (if they are not also a square)
An equilateral triangle contains at least 2 lines of symmetry (it actually contains 3 lines of symmetry). An equilateral triangle is also radially symmetric.If the question is "Is there a triangle with exactly 2 lines lines of symmetry?", the answer is no.
