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.

In a square made up of sixteen smaller squares, there are a total of 30 squares. This includes the one large square, the sixteen smaller squares, nine squares formed by combining four smaller squares, and four squares formed by combining nine smaller squares. Each of these squares contributes to the total count of 30 squares within the larger square.
