Level C 1. The window has four right angles. The correct answer is: B. False. There are 5 window panes each with four right angles making 20 in total. 2. The sign has no right angles. The correct answer is: A. True. 3. There are 8 right angles in one tile. The correct answer is: B. False. Each tile as 4 right angles. 4. There are 8 right angles in the sign. The correct answer is: B. False. Inside the black shape there are 6 right angles. If we were to count the right angles in the white shape that would be 4 more.so the answer is either 6 or 10 depending upon what is counted. 5. There are four right angles in the flag of Bahamas The correct answer is: B. False. There are more than four. Each strip of colour has two right angles which add up to 6 in total. 6. There are six right angles in the hexagonal tables. The correct answer is: B. False.
7. There are more than ten right angles in the Swiss flag. The correct answer is: A. True. There are 8 right angles within the white section, here are then 4 more within the red section of the cross and 4 more in the corners. 8. There are four right angles in the road sign. The correct answer is: A. True. This is correct with two at each end of the black shape. 9. There are more than four right angles in the St Lucian flag. The correct answer is: A. True. 10. There are eight right angles in the kite. The correct answer is: B. False. The main kite shape has no right angles. The cross at the centre might have some right angles although only 4 as a maximum.
