In class we have been learning about different angles, we have been learning the names of them, why we have different angles, and what is the difference between each of them. We have been doing whole class lessons on them and have been doing worksheets to understand them more.
Mrs Cutler found protractors for us to use to get the correct measurement and to figure out what it is, the 3 we have been mainly working on is Acute, Obtuse, and right angle, the teacher taught us what the differences were, an Acute is an angle that is less than 90°, and Obtuse is an angle that is larger than 90°and less than 180°, and a right angle is exactly on 90°.
How we use protractors is to measure from the the center semi circle and out, make sure that the 90° line I your middle point, if it isn't you would have incorrect measurement.
The symbol ° means degree, a degree is something you use when measuring angles and temperature, if you don't add the degree symbol then you would be marked wrong because if the answer was 50° people sometimes just put 50 and that could pretty much mean anything so you have to have the symbol when dealing with angles.
The worksheet we had to fill in looked kinda hard but once you knew how to use a protractor properly it became more understandable, the worksheet was a mix of Acutes, Obtuse, and Right Angles, so that is why we need to use the protractors, we then had a little break from angles.
Later on we went outside and Mrs Cutler then told us to point out angles that we could see, the ones we saw we measured, she then told us to take a protractor and got around the school and try and find different angles and figure out what the angles is, Holly and I were buddies and we went around the school and we were mostly finding Right Angles, but we did eventually find a few Acutes.
