Angle Information
• Acute Angles – measure less than 90º
• Right Angles – measure exactly 90º
• Obtuse Angles – measure more than 90º but less than 180º
• Straight Angles – measure exactly 180º

Angles TaskActivity
• For this activity, you will be paired up with a partner to visit the following website.
• After clicking below, skip the intro and click on the Make the
Angle Game.
• You and your partner must make 10 angles and record them on a sheet of paper.
• Once you have recorded 10 angles, tell what type of angle it is.
