A strip heater
I would claim that a straight line is slightly bend as we define straight from the horizon.
I classify a parallel line as two line segments that will never intersect if the line kept going. They are perfectly straight and even.
Curve is one possible opposite of straight if straight refers to line that does not bend. Other meanings of straight like honest, heterosexual, and direct have different opposites than curve.
The radius of a circle is a line segment joining any point of the boundary of the circle to its centre. A diameter is a line segment from a point of the boundary of the circle which passes through the centre and ends at the boundary on the opposite side.
Yes. If it is not straight, then it is not a line.
Strip heater-to heat up the acrylic so that you can bend straight line edges into it Acrylic drill bits-so that it is easier to drill through the acrylic Square- to check that everything is lined up correctly and is straight Solvent cement-is used to join pieces of acrylic together

straight line
light travels in a straight line because it can only be bend by reflective objects.
Light travels in a straight line. The path of light can be bent by very massive objects because they actually bend space.
Normal. It takes a lot of mass to bend light.
Gravity. (Or the shape of space - which is molded by gravity.)

draw a line lightly with a ruler then follow it. that's what i do.
Normally light travels in a straight line. However, it has been demonstrated that gravity can bend the path of light.
