When we look at triangles, it's really interesting to see how the lengths of their sides tell us what kind of triangle it is. There are three main types of triangles based on their side lengths: scalene, isosceles, and equilateral.
A scalene triangle has all three sides of different lengths. This means that none of the sides are the same, and because of that, all three angles are different, too.
For example, if a triangle has sides that are 3 cm, 4 cm, and 5 cm long, it’s a scalene triangle. The angles in this triangle can also be different, but they will always add up to 180 degrees.
Next is the isosceles triangle. This triangle has two sides that are the same length.
For instance, if two sides are 5 cm long and the third side is 3 cm long, that makes it an isosceles triangle. A cool thing about isosceles triangles is that the angles opposite the equal sides are also equal. So, in our example, the angles across from the 5 cm sides will be the same.
Now, let's talk about the equilateral triangle. This is a special type because all three sides are equal.
If each side is 6 cm, then all the angles in the triangle will also be the same, measuring 60 degrees each. So, with an equilateral triangle, every side and every angle is equal, making it perfectly balanced.
Here’s a quick recap of the types of triangles based on their side lengths:
Understanding these types of triangles helps us figure them out easier and is really important in geometry. So, the next time you see a triangle, take a moment to check its sides—they reveal what type it is!
