Today I will be helping you with defining the angles of a triangle.When looking at a triangle, it can either be Right, Obtuse, or Acute.
A right triangle means there is one 90 degree angle in the triangle, that would look like this.
The square in the bottom left corner means that angle is exactly 90 degrees, which is what makes it a right triangle. A super simple way to be able to tell if it is a right triangle or not is to see if it has an "L" or not. If there is a perfect "L", then it is not right. A great visual tool to be able to tell this is if you stick one arm straight up in the air, and the other arm straight to the side.
An obtuse triangles is one that has an angle that is larger than 90 degrees. If there is even a single angle that is larger than 90 degrees, the triangle is automatically obtuse. This is what an obtuse triangle looks like.
An acute triangle is the opposite. It is when all of the angles are less than 90 degrees. That looks like this.
If you were to stick your arms out to make a right triangle, this shape would be smaller than that. That is a really simple way to identify an acute triangle.
To learn more, please go here: Acute, Obtuse and Right Triangles. I hope you all learned something from this, because my next post is going to be going off of this one!! See you next time!

Hello,
ReplyDeleteI really liked in this post how you added a picture of each of the types of triangles so that after they read about that specific triangle, they can see what it looks like. I also really liked how you explained each one of the triangles and went into detail with it instead of just saying this is what an acute triangle looks like. That you described each of the angles and how you know if it is acute, obtuse or a right angle. Awesome job!

Awesome job! Loved how you went into detail on your blog and made it as an educational teaching tool, maybe that was my malfunction. I kept thinking of it as a blog and what I do in my daily life, not to teach someone. Maybe a Blog is the wrong kind of wording or it needs to be explained better, at least for some of us. lol
ReplyDeleteI like how you broke everything down for each post and explained in detail, that was cool, you were teaching to us and didn't even know it. I love how you made it interactive in a way to engage the reader more but saying you hope they learned something then backing it up with what they could learn next. Great job!
