It is designed to easily cut curves. Whether it cuts in straight or curved lines depends how good the user is: a good user will be able to use it to cut straight lines, but a not-so good user will tend to "wobble" and so cut lots of little curves when trying to cut in a straight line.
Think about this: A straight angle makes 180 degrees, right? Straight lines, when measured by a compass, are also 180 degrees. So, yes, all straight angles are straight lines.
No. A circle has no straight lines. You can approximate circles with very small straight lines (that's how a computer draws circles) but mathematically, no.
No, all polygons have straight lines. All lines are straight

A jigsaw is used for cutting curved or round holes. With a straight guide it can cut straight lines.
Either cut along three non-intersecting lines or two intersecting lines. The lines need not be straight.
No, because, none of the combinations of lines can evenly slit spaces. Fold the circle first, and then you can cut the circle into 5 pieces with 2 straight lines.
A hacksaw is a hardened, toothed blade, fixed into a metal frame that has a handle. The hacksaw is used to cut through metal.
A hacksaw.
Cut with it. (Pffffft.)
A junior hacksaw is simply a small hacksaw. There are not so many choices for blades, however it can do essentially anything that a full size hacksaw does, but in a smaller space.
You can cut a round cake into eight parts with three cuts, but you can't cut a circle into eight parts with three straight lines.
A pizza can be cut into eleven pieces with 4 straight cuts if an X is cut, then the rest of the pizza is cut starting from the right and working to the left in four straight lines.
I just use a hacksaw.
