In this activity, we'll take a look at right angles.
A right angle is an angle that is equal to 90°.
Here is a right angle.
We can see it's marked with a rectangle corner marker.
If you see an angle marked with a square or rectangle, it's a right angle.
Is this angle larger or smaller than a right angle?
The angle above is marked with a curved angle marker and it is larger than the example of a right angle.
Think about the corner of a rectangle, which is a right angle.
The angle we are shown is much larger than the rectangle's corner.
So, the angle above is larger than a right angle.
