Hmm pizza! Oh sorry, focus!
So I think today, we are looking at angles.
Great! You鈥檙e cutting that pizza at right angle. That means the angle is 90 degrees.
Nice big piece for square. So what next?
You鈥檙e cutting that one at an obtuse angle. That means the angle is between 90 and 180 degrees.
Not bad eh?
Lastly, you鈥檙e going for an acute angle. That鈥檚 one that鈥檚 less than 90 degrees.
Bad luck. So each time you cut these you are left with a reflex angle on each pizza.
This is any angle that is greater than 180 degrees. And I wonder who got those ones鈥
Mmhmm. Might have guessed really.
An angle is a measure of a turn, measured in degrees or 掳. There are 360掳 in a full turn. You can find out the size of an angle using a protractor.
- An angle less than 90掳 is acute.
- An angle between 90掳 and 180掳 is obtuse.
- An angle greater than 180掳 is reflex.
- An angle of exactly 90掳 is a right-angle.
