[size=150][b][color=#980000][size=200]Triangles can be classified by the number of sides that are congruent.[/size][br][/color][/b][/size]

[size=150][b][color=#38761d]A triangle with all three sides congruent is an [/color][color=#ff0000][size=200]Equilateral Triangle[/size][/color][color=#38761d]. All three angles of an equilateral Triangle are congruent. [/color][/b][/size]

[size=150][b][color=#38761d]A triangle with at least two sides congruent is an [/color][color=#ff0000][size=200]Isosceles Triangle[/size][/color][color=#38761d]. The two angles adjacent to the congruent sides are congruent. [/color][/b][/size]

[size=150][b][color=#38761d]A triangle with no sides congruent is a [/color][size=200][color=#ff0000]Scalene Triangle[/color][/size][color=#38761d]. None of the angles in a Scalene Triangle are congruent. [/color][/b][/size]
