Answer:
A two dimensional figure that has only one endpoint is a ray
Step-by-step explanation:
A ray has one endpoint and then goes on for infinite time in the other direction.
It is an irrational number. That is because rational numbers can be put into fractions. But because this decimal goes on forever, you can't put it into a fraction. This is also not a whole number or an integer. Whole numbers and integers do not have any decimals or fractions in them, but this number is a decimal. Therefore, this number is irrational.
