			In this section the laying of tiles will be used as an example of when you may need to check right angles.

			Step 1 – Find right angle Locate the 90° angle (right angle) on the folding square.

			Step 2 – Position folding square Place the corner of the 90° angle (right angle), against the corner you are checking.

			Step 3 – Line up folding square Push the corner of the folding square (90° angle) firmly against the corner of the tiles.

			Step 4 – Check work Check if the sides of the folding square are flush against either side of the tiles. Here, the term ‘flush’ essentially means that there will be no gap on either side of the square, with the right angled edges fitting perfectly.

			If each side is flush against the corner, then it’s a 90° angle (right angle).

			If there is a gap between the sides of the folding square and the sides of the tiles then it is not a right angle. This can be a result of the tiles not being cut correctly or of the edge where you started laying tiles not being straight.
