a) State whether each statement is true or false.
i) Polygon N'R'E'Q' is a reflection of polygon NREQ.
ii) Polygon N'R'E'Q' is a rotation of polygon NREQ 180° about the origin.
iii) Polygon N'R'E'Q' Is a rotation of polygon NREQ 90° anti-clockwise
about the origin.
iv) Polygon N'R'E'Q' is a rotation of polygon NREQ 90° clockwise about the origin.
b) Draw polygon N'R'E'Q'on a piece of graph paper.
