A square has four corners, so it has four angles. A triangle has three corners, so it has three angles. Count the corners to count the angles. *(drawing: A triangle has three corners. A square has four. Each corner is an angle.)* **Example.** Ali swings his bedroom door open. A door that turns a little makes a small angle. A door that turns a lot makes a big angle. Two doors that turn the same amount make the same angle, whatever their size. A quarter turn, like a clock hand going clockwise from 12 to 3, makes a square corner angle. *(drawing: At 3 o'clock the hands make a square corner opening. The short hand points at 3 and the long hand points at 12.)* From least to most turn: tiny turn, quarter turn, half turn, full turn. A full turn is four quarter turns. Keep going the same direction to turn more than a full turn. Turns add up when you turn the same way. A quarter turn clockwise takes the hand from 12 to 3. A half turn clockwise takes it from 12 to 6. A full turn is four quarter turns. A quarter turn and a half turn clockwise take it from 12 to 9. From 3, a quarter turn clockwise reaches 6. **Recap.** An angle is the corner a shape makes, or the amount something has turned: big turns make big angles, small turns make small angles. ## Practice 33 questions on this page, each with its working shown. ## Needs first - [2-D shapes (age 6+)](https://lightmysky.com/learn/mathematics/2-d-shapes-age-6-mt_sBcRdUfAzV) - [Position, direction, and movement](https://lightmysky.com/learn/mathematics/position-direction-and-movement-mt_TdV9YGJEoY) ## Opens up - [Right Angles & Turns](https://lightmysky.com/learn/mathematics/right-angles-and-turns-mt_MFfYcnv6Tv)
