Identifying missing coordinates of shapes

Maths

Transformations

I must have all 4 coordinates of the vertices of a square

If I have 3 out of 4 coordinates of the vertices of the square, then I cannot find the last one

If I have any 3 out of 4 coordinates of the vertices of a square, then I can easily find the last one

If I have the coordinates of 1 of the vertices of a square, then I can find the coordinates of the remaining three vertices

Which of the following statements is correct?

(5,4), (9,8) and (5,8) are the coordinates of three vertices of a square, what are the coordinates of the last?

(1,-10), (9,-10) and (9,-4) are the coordinates of three vertices of a rectangle, what are the coordinates of the last?

(-4,6) and (-2,8) are the coordinates of two vertices of a square, what are the coordinates of the remaining two vertices?

(7,6) and (13,3) are the coordinates of two vertices of a right angled triangle, what are the two possibilities of the coordinates of the third?

The reflected shape has the same x coordinate as the original shape

The reflected shape has the same y coordinate as the original shape

Which of the following happens when a shape is reflected by a line of reflection along the x-axis?

Both the x and y coordinates of the reflected shapes must change

Both the x and y coordinates of the reflected shapes must stay the same

The x coordinate will definitely stay the same

The y coordinate will definitely stay the same

If  a shape is reflected by a line of reflection along the x axis then which of the following is correct?

The triangle has been reflected onto the x-axis

The triangle has been reflected onto the y-axis

If a triangle has the coordinates (1,3), (1,4), (2,3) and after a transformation becomes (1,-3), (1,-4) and (2,-3), which if the below have happened?

If a triangle which has the coordinates (1,-1), (1,-3) and (3,-3) is reflected by a line of reflection along the y-axis, what will it's new reflected coordinates be?

A triangle with coordinates (-2,-2), (-2,-4) and (-4,-4) is reflected first by a line of reflection along the x-axis, and then reflected by a line of reflection along the y-axis, what will the new coordinates be?
