9 obvious, 3 for each row, 3 for each column, 4 for each rectangle of 4 squares, all of the squares. So 19
Draw diagonal lines to form a diagonal cross in each square, so dividing all the squares into four triangles in each. A pencil and a straightedge is all that is needed, no measuring to form vertical and horizontal lines to divide each square into four smaller squares is required. Can't show a photo or graphics in Answers, I believe.
Squares always have 4 interior angles which each measure 90°; rhombuses do not.
There are 28 squares because each square has 4 sides and so multiply 4x7=28
Yes
4 white squares and 4 black squares on each row
I think it would be 2x2 squares
There are 12 squares. It can be notes as 4 rows across with 3 squares in each, or as 3 rows down with 4 squares in each.
Yes, because all squares have four equal sides.
Divide square into 4parts gets 4 rhombus shapes
No. You can only divide a square into 4, 9, 16 etc (i.e. they must be square numbers.

3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.

Assuming each of the smallest squares (i.e., each of the 16 ones forming the large square) has a side 1 unit long: There are 16 squares that are 1x1. There are 9 squares that are 2x2. There are 4 squares that are 3x3. And there is 1 square that is 4x4. So the total number of squares is 30.
