What is an angle?• An angle is when two straight
half-lines (rays) meet together at an endpoint they share called a vertex.

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

Student AssignmentNow that you have learned what the angles are and what they look like, your assignment is:
Use a digital camera to make a Glogster poster about angles you found around your community. Be and let your personality show.
CREATIVE
Core StandardsMath Standard 3- Students will describe and analyze attributes of two-dimensional shapes.
Objective 1.d- Identify right angles in geometric figures, or in appropriate objects, and determine whether other angles are greater or less than a right angle.
Intended Learning Outcomes:*Connect mathematical ideas within mathematics, to other disciplines, and to everyday experiences.*Represent mathematical ideas in a variety of ways
