When constructing an inscribed square, how many lines will be drawn in the circle? •2 •3 •5 •7

Option A.

Step-by-step explanation:

We need to find the number of lines that will be drawn in the circle to construct an inscribed square.

The steps for constructing an inscribed square in a circle are

1. Draw a circle.

2. Make a diameter of that circle.

3. Draw the perpendicular bisector of that diameter.

4. Now marks the intersection points of these two lines are circle.

5. Connect these 4 intersection points consecutively by straight lines.

Diameter and a perpendicular bisector of diameter are two lines which that will be drawn in the circle to construct an inscribed square.

Therefore, the correct option is A.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
