Over the past few weeks we have been learning about different types of angles. The picture on the left shows a lot of angles! I can see an acute angle, right angle, and 180° or straight angle. I can see acute angles where two lines meet and an angle is made that is less than 90°. Then I can see a right angle where two lines make the corner of a square or rectangle. Last but not least I can see straight angles everywhere (a straight line).
When we were learning about angles with Ms. Rogerson, we learned protractor measurment, rotations in gymnastics, we took digital pictures of angles in our environment, and then measurment of these angles.
Now it’s your turn to take a look at the picture. Can you see any angles?
These are the angles we learned about:
- 180°- Straight angle (straight line)
- 90°- Right angle (line up and across)
- Obtuse – Greater than 90°
- Acute – Less than 90°
- Reflex – Outside of an angle
Learning about angles was pretty fun! Taking pictures of different angles on the playground, in the classroom, and in the halls was my favourite activity.
Do you know any other angles that I didn’t put down? Can you find any in your environment?
