What type of angle is it?

Objectives Understand the different types of angles Acute Right Angle Obtuse Straight Angle Reflex Draw angles correctly

Vocabulary Angle West Whole Right Angle Clockwise 360º Degrees Anti-Clockwise 180º Position Horizontal 90º Direction Vertical 45º North Grid East Turn South Compass

Using your Compass N W E S

Acute Angle Acute angles are less than 90o.

Right Angle Right angles are 90o

Obtuse Angle Obtuse angles are more than 90o but less than 180o.

Straight Angle Straight angles are180º.

Reflex Angle Reflex angles are more than 180o.

Remember… Acute angles are less than 90o. Right angles are 90o. Obtuse angles are more than 90o but less than 180o. Straight angles are 180º Reflex angles are more than 180o.

Success Criteria I can understand the difference between an acute, right angles, obtuse, straight and reflex angles. I can measure correctly? I can label correctly? Can I use a protractor?
