Creative Thinking
1 A triangle and a square are placed side by side on line AB. If the
square does not move, and the triangle slides towards the square along
line AB, what polygons can be formed when the two figures overlap?
AB
2 A mirror is placed perpendicularly on a piece of paper with 9 dots. The
sum of the dots on the paper and the dots reflected in the mirror is 18.
Draw lines to indicate where the mirror can be placed such that the
sum of the dots on the paper and the reflected number of dots is 11.
Explain how you found your answer.
