Level 3 · Challenge
7 A pentagon and a triangle are placed side by side. How many sides do they have altogether?

A pentagon has 5 and a triangle has 3, so 5 + 3 = 8 sides.
8 A shape has 5 sides and none of them are equal. What is it called?
Show worked solution
Five sides makes it a pentagon, and unequal sides makes it irregular pentagon.
9 How many MORE sides does an octagon have than a pentagon?

An octagon has 8 and a pentagon has 5, so 8 − 5 = 3 more.
⭐ Bonus Challenge · only if the rest felt easy
