Classifying Triangles Song https://www.youtube.com/watch?v=bCuxvgCo0Jc A triangle has 3 sides The angles inside add to 180 There are ways to classify By their sides And the angles inside Isosceles Scalene Equilateral Acute Obtuse Or Right Triangle But we won’t know Until we know just what that means Are there no equal sides Or are there 2 or 3 Are the angles greater than or less than 90 Or is there one that measures exactly We’ll always be triangles It’s our polygonal family If we treat sides equally Equilateral is what we’d be We could be scalene And have no equal sides Or we can have 2 And be an isosceles Angles are 89 or less An acute is what it is If just 1 is all or greater It’s obtuse If it’s 90 It’s the right you’ll choose Isosceles Scalene Equilateral Acute Obtuse Or Right Triangle But we won’t know Until we know just what that means Are there no equal sides? Or are there 2 or 3 Are the angles greater than or less than 90? Or is there one that measures exactly We’ll always be triangles It’s our polygonal family If we treat sides equally Equilateral is what we’d be We could be scalene And have no equal sides Or we can have 2 And be an isosceles We’ll always be triangles It’s our polygonal family If we treat sides equally Equilateral is what we’d be We could be scalene And have no equal sides Or we can have 2 And be an isosceles
