How are Angles Measured in Degrees? | Don't Memorise?

Imagine your arms are like a clock, when you stretch them wide, that’s 360 degrees, like a full circle!

When we measure angles in degrees, it's like dividing a pizza into slices. A whole pizza is 360 slices, and each slice is one degree. If you take just one bite, that’s about 1 degree, tiny!

How We Count the Slices

We use a tool called a protractor to measure angles. It looks like a semicircle with numbers from 0 to 180, kind of like a ruler for angles!

  • If you put your arms straight out, that’s 90 degrees, like one-quarter of the pizza.
  • If you bend them in, it’s less than 90, maybe like 45 degrees if you're halfway between straight and hug-style.

Why 360?

Why not 100 or 200? Well, 360 is a number that works nicely with many other numbers, kind of like how 12 works well with hours on a clock. It makes dividing the circle into parts easier for us to count and understand.

So next time you eat pizza or play with your arms, remember, you're measuring angles in degrees, just like a pro! 🍕Imagine your arms are like a clock, when you stretch them wide, that’s 360 degrees, like a full circle!
