Time to Take on Triangles!
Wouldn't it be nice if we could go back to our Kindergarten days where identifying a triangle meant that the shape had three sides and three points? I miss that...
Now we know there are many different types of triangles! They each are identified differently and have certain characteristics that classify them as a certain type of triangle. When we started this Geometry unit I could only remember four types of triangles: Right, Isosceles, Acute, and Obtuse. However, I couldn't remember how to identify these triangles either. Upon further research I discovered that there are two other triangles: Equilateral and Scalene.
I found a great video from Khan Academy that gave me lot of good information on these triangles.
I didn't realize before that Scalene, Equilateral, and Isosceles triangles are triangles that are triangles that have equal sides or at least two sides that are equal. Acute, Right, and Obtuse triangles are triangles that are classified by their angles. There are a few ways to identify these triangles and certain characteristics they hold, so I'll just give a brief description of each of them.
Equilateral: All three sides of the triangle are equal.
Isosceles: This triangle has at least two equal sides.
Scalene: There are no equal sides on this triangle.
Right: Has one angle that is 90° and the other two angles are acute angles.
Acute: Has three angles that will measure up to less than 90°.
Obtuse: Has one angle that is bigger than 90° and the other two angles are acute angles.
So you see, there's definitely a lot more to triangles other than the fact that they have three sides and three points. We can still be envious of those Kindergarten days though...
Here's a really great triangle activity/worksheet that would be great to use in a classroom, Classifying Triangles. Hope you learned a little more about triangles in this post!
