  2. Angles 1. How many degrees are there in one full turn? 180 90 360.

  3. 2. Imagine you're facing north. You turn clockwise through 90 degrees. Which direction are you facing now? East South West

  4. 3. Imagine the capital letter M. What letter does it look like when it's rotated 180 degrees? E W M

  5. 4. An angle less than 90 degrees is obtuse acute reflex

  6. 5. Which of these is a reflex angle? 145 degrees 45 degrees 245 degrees

  10. 9. Will two parallel lines ever cross? Yes No Depends on how they are drawn

  11. 10. Angles are measured using a compass ruler protractor

  12. Correct. You're absolutely right. 90 degrees is a quarter turn. Turning 90 degrees clockwise would turn you from facing north to facing east. 3. Imagine the capital letter M. What letter does it look like when it's rotated 180 degrees? You said: W Correct. 180 degrees is a half turn. Rotating an M through a half turn would turn it into a W. 4. An angle less than 90 degrees is You said: acute Correct. Yes, any angle between 0 degrees and 90 degrees is called an acute angle. 5. Which of these is a reflex angle? You said: 245 degrees Correct. A reflex angle is any angle between 180 degrees and 360 degrees. 6. An angle between 90 degrees and 180 degrees is You said: obtuse Correct. Yes, any angle between 90 degrees and 180 degrees is called an obtuse angle. 7. If two of the angles inside a triangle are 90 degrees and 50 degrees, what is the third angle? You said: 40 degrees Correct. The three angles inside a triangle always add up to 180 degrees. So it had to be 40, as 90 + 50 + 40 = 180. 8. Are the lines in the capital letter L parallel or perpendicular? You said: Perpendicular Correct. You realised that the lines in an L meet at right angles to each other, so they must be 180 degrees is a half turn. Rotating an M through a half turn would turn it into a W. 4. An angle less than 90 degrees is You said: acute Correct. Yes, any angle between 0 degrees and 90 degrees is called an acute angle. 5. Which of these is a reflex angle? You said: 245 degrees Correct. A reflex angle is any angle between 180 degrees and 360 degrees. 6. An angle between 90 degrees and 180 degrees is You said: obtuse Correct. Yes, any angle between 90 degrees and 180 degrees is called an obtuse angle. 7. If two of the angles inside a triangle are 90 degrees and 50 degrees, what is the third angle? You said: 40 degrees Correct. The three angles inside a triangle always add up to 180 degrees. So it had to be 40, as 90 + 50 + 40 = 180. 8. Answers 1. How many degrees are there in one full turn? You said: 360 Correct. There are 360 degrees in a full turn. 2. Imagine you're facing north. You turn clockwise through 90 degrees. Which direction are you facing now? You said: East Correct. You're absolutely right. 90 degrees is a quarter turn. Turning 90 degrees clockwise would turn you from facing north to facing east. 3. Imagine the capital letter M. What letter does it look like when it's rotated 180 degrees? You said: W Correct. 180 degrees is a half turn. Rotating an M through a half turn would turn it into a W. 4. An angle less than 90 degrees is You said: acute Correct. Yes, any angle between 0 degrees and 90 degrees is called an acute angle. 5. Which of these is a reflex angle?

  13. correct. You're absolutely right. 90 degrees is a quarter turn. Turning 90 degrees clockwise would turn you from facing north to facing east. 3. Imagine the capital letter M. What letter does it look like when it's rotated 180 degrees? You said: W Correct. 180 degrees is a half turn. Rotating an M through a half turn would turn it into a W. 4. An angle less than 90 degrees is You said: acute Correct. Yes, any angle between 0 degrees and 90 degrees is called an acute angle. 5. Which of these is a reflex angle? You said: 245 degrees Correct. A reflex angle is any angle between 180 degrees and 360 degrees. 6. An angle between 90 degrees and 180 degrees is You said: obtuse Correct. Yes, any angle between 90 degrees and 180 degrees is called an obtuse angle. 7. If two of the angles inside a triangle are 90 degrees and 50 degrees, what is the third angle? You said: 40 degrees Correct. The three angles inside a triangle always add up to 180 degrees. So it had to be 40, as 90 + 50 + 40 = 180. 8. Are the lines in the capital letter L parallel or perpendicular? You said: Perpendicular Correct. You realised that the lines in an L meet at right angles to each other, so they must be perpendicular lines.EXT
