Acute Angle - Definition with Examples
What is an acute angle?
In geometry, an acute angle is an angle which measures less than 90 degrees (90°).
Here, ∠PQR measures 45 degrees (45°) and thus, is an acute angle.
We can find an acute angle in a stapler, a pair of scissors, and in a geometric compass, around us.
Acute angles are the small ones! You see!
They are always smaller than 90 degrees.
Let's do it!
Instead of handing out math geometry worksheets on angles, ask children to observe/spot things around them in which they can see acute angles.
You can also ask them to make acute angles using their arms and fingers.
