Hmm pizza! Oh sorry, focus!
So I think today, we are looking at angles.
Great! You’re cutting that pizza at right angle. That means the angle is 90 degrees.
Nice big piece for square. So what next?
You’re cutting that one at an obtuse angle. That means the angle is between 90 and 180 degrees.
Not bad eh?
Lastly, you’re going for an acute angle. That’s one that’s 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…
Mmhmm. Might have guessed really.
An angle is a measure of a turn, measured in degrees or °. There are 360° in a full turn. You can find out the size of an angle using a protractor.
- An angle less than 90° is acute.
- An angle between 90° and 180° is obtuse.
- An angle greater than 180° is reflex.
- An angle of exactly 90° is a right-angle.
