Is 2 by 2=4 rational or inrational and why

 Rational

Step-by-step explanation:

A rational number is an integer divided by an integer where the result is a terminating or repeating decimal.

2 x 2 = 4    --> 4 is terminating  so it is a rational number.

If you are in a higher level math class, the reason is:

Rationals are CLOSED over multiplication.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
