A tangent line is a line that is parallel to and intersecting a point on a curve, where the limit of the distance between two points on that curve (one of them being the point in question) and those two points also being on that line approaches zero.
Since a straight line has only one slope, at all points on the line, then there can only be one tangent line to a straight line, and the tangent line is the same line as the straight line.

How do you draw quadrilaterals?
Four straight lines
Do you use scale to draw a straight line?
I looked up and I think you use them to draw graphs but can use them to draw straight lines.
How do you draw a straight line form any point to another?
You can draw straight lines with the help of a ruler or anything with a straight edge.
How do you draw a curve with straight lines?
While a curve is one continuous motion, you can create the illusion of a curve by using straight lines. In order to do this, draw a continuous pattern of short straight lines, while changing the direction of each line slightly.
Which instrument can help to draw straight lines?
The most common tool used to draw straight lines is the age old ruler. If you don't have a ruler you can also substitute it with any straight edge found nearby.
