Types of Basic AnglesThere are three basic angles

we are going to learn. *Right Angles*Acute Angles*Obtuse Angles

*Click on each angle to learn more

Right AnglesA right angle comes together with one vertical line meeting one horizontal line at a 90 degree angle.

It looks like thisA square has

4

right angles!

Acute Angles Acute angles are like baby angles and

are cute!

They are always less than 90 degrees

“A” for acute angle

Obtuse Angles Obtuse angles are wider than 90

degrees

The “O” in obtuse reminds us it is

Open wide
