Three triangles are:
scalene, which has three sides of different lengths,
isosceles, which has two sides with the same length, and
equilateral, which has three sides that are all the same length.
In the picture, the scalene triangle is triangle RST, the isosceles triangle is triangle XYZ, and the equilateral triangle is triangle ABC. If two sides or more sides of a triangle have a little line on them, then they are the same length. Click on the related link, "Three Triangles", to see them.
