Shade two more squares so that this grid has rotational syminetry of order 4.

1) bottom row, next to the last (4th square going across)

2) second row, first square (1st column, next to the bottom)

Step-by-step explanation:

1) bottom row, next to the last (4th square going across)

2) second row, first square (1st column, next to the bottom)

can you me with homework?

step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
