An equilateral triangle has all the sides the same length as each other. (Equilateral sounds like ee-quee-lat-ral.)
Play with the equilateral triangle to the right. Make it bigger and smaller. Move it around. Can you make one side go straight up and down?
Whatever you do with it, it will still be an equilateral triangle, because all the sides are the same length as each other.
On a piece of paper, draw some of the equilateral triangles you made. Make sure you label your drawings "Equilateral triangles".
