Help please!!

How many lines of symmetry does the following figure have?
1) 16
2) 2
3) 8
4) 4

4

Step-by-step explanation:

Symmetry is when you can flip the figure over a line and it will perfectly match the other side.

We see that if we draw a vertical line down the middle and a horizontal line across the middle, we get mirror images. So that's 2.

Then notice that we can draw two diagonals across the image, one from the upper left corner to the lower right corner and the other from the upper right corner to the lower left corner. That's another 2.

We try to find more, but try as we might, there are no others to be found.

Thus, there are 4 lines of symmetry.

Hope this helps!

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.
