If you said triangle, you got it! But what kind of triangle is it? Did you know that there's more than one type of triangle? It's true! Thanks to the great minds of geometry over the ages, the simple three-sided triangle has been further defined in a variety of ways. In addition to three sides, every triangle also has three angles. read more
Mathematicians have given triangles special names based upon how many of those angles are equal. For example, an equilateral triangle has three equal angles (and three equal sides). Each angle in an equilateral triangle equals 60º, since three 60º angles would add up to 180º. read more
You can categorise types of triangles into 4 different types depending on the sides/angles. Note: the sum of interior angles in a Triangle is equal to 180°. Equilateral - all three sides and angles are equal. read more
Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles: read more
