A symmetrical shape is a mirror image of a shape when a line is drawn through it and some shapes have many lines of symmetry or none at all.
None. A line of symmetry, if it exists, is infinitely long and so a third of the line cannot exist as a separate entity.
You would call the group of shapes which has at least one line of symmetry symmetrical shapes. Stars, circles, and rectangles are considered symmetrical shapes.
This is either a trick question or a silly question. A rectangle comprises four line and so cannot be drawn with three lines.
Horizontal
A construction line is a line very lightly drawn and is used as a guide to help draw all other lines and shapes properly.
The ideal line is a concept. A line that is drawn cannot be a mathematically true line since it will have a thickness - no matter how small. Also, it cannot be infinitely long - no matter how large.

A construction lines are a lightly drawn lines that aid in drawing all other lines or shapes properly. An example of a construction line are those on a sheet of graph paper. These lines are lightly drawn and they help with the construction of shapes and figures. Construction lines are also useful in Multiview Drawings. They are projected from one figure and help the drawer make another figure. These lines are erased afterwards.
a line of symetry can be applied to one shape but cannot go between two shapes unless those two shapes are infact a part of one larger, symetrical shape. a line of reflection goes between two shapes. so O l O this is two circles with a line of reflection in between them. if there was a line of reflection between two e's then one of the e's would have to be a backwards e.
line-drawing
There is only one line (or line segment) that can be drawn between two distince points.
The line is called a diagonal if it is drawn between two nonadjacent angles.
Positive shapes
You would call the group of shapes which has at least one line of symmetry symmetrical shapes. Stars, circles, and rectangles are considered symmetrical shapes.
All regular shapes have a line of symmetry. But you can get rid of its line of symmetry by making it irregular (so the angles aren't the same).
