Classifying Angles – acute, right, obtuse, etc.Measuring Angles: Foundation – Identifying fractions of a circle (From Worksheet).Measuring Angles (From Example/Guidance).
The base line of the protractor should coincide. The centre of the protractor is placed on the vertex B of the angle ABC. Thus, we will use the inner scale to measure the angle. Read the number off the protractor where the second side of the angle meets the protractor. Place the protractor so that one of the lines of the angle you want to measure points to 0.
Geometric measurement: understand concepts of angle and measure angles Measuring an angle using a protractor in anticlockwise direction: This is measurement in anticlockwise direction. Place the origin or center point (usually a small hole) of the protractor exactly where the sides of the angle meet.
Similar to the above listing, the resources below are aligned to related standards in the Common Core For Mathematics that together support the following learning outcome: Measure angles in whole-number degrees using a protractor. The various resources listed below are aligned to the same standard, (4MD06) taken from the CCSM ( Common Core Standards For Mathematics) as the Geometry Worksheet shown above.
