Verify Expreimentally that if all sides and all angles of a quadrilateral are equal then it is the square​

It only matters what the angle is. If all the angle is 90 degree than it is a square. But, if it is not 90 degree than it is not a square.

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

answer: for each 3 girls there is 2 boys . 3: 2
