On the left is an equilateral triangle.[br][size=150]An [b]equilateral triangle[/b] is a triangle with three equal length sides.[br][br]On the right is an isosceles triangle.[br][/size][size=150]An [b]isosceles triangle[/b] is a triangle with two equal length sides.[/size][br][br]Change the side lengths of the triangle by using the Slider.[br]Then, answer the questions at the bottom.
What do you notice about the angle measurements of different sized [b]equilateral triangles[/b]?
If a triangle as [b]two 60 degree angles[/b], what must be true about the side lengths of that triangle?
