1. A square number is

Square numbers are the result of squaring an integer (IxI)

Cube numbers are the result of the cube of an integer (IxIxI)

A triangular number is a number such that the shape of an equilateral triangle can be formed by the number of dots.

Is this OK? Next one is?

Oops the dots didn't work.

I usually illustrate triangular numbers with the example of setting up a triangle of billiard balls

with 1 row you have 1 ball

with 2 rows you have 3 balls

with 3 rows you have 6 balls

with 4 rows you have 10 balls

etc.
