An introduction to the fundamental concepts of shapes, sizes, and the properties of space.
Angles are formed where two lines meet, and they help us describe turns, corners, and rotations.
Angles are everywhere—from the corners of a book to the hands of a clock!
Use a protractor to measure angles in degrees (\(^{\circ}\)).
Angles help us create ramps, design roads, and even play sports!
\[\text{Angle in degrees} = \frac{\text{Arc Length}}{\text{Radius}} \times 57.296\]
The corners of a square are right angles.
A pizza slice has an acute angle at the tip.
Angles describe how much two lines turn where they meet.
