Note that reflecting triangle ABC with respect to the x-axis, and translating it 3 units down, mapps it perfectly to A'B'C'.
Thus, the answer is: <span>△ABC is congruent to △A′B′C′ because you can map
</span>
△ABC to △A′B′C′ using a reflection across the x-axis followed by a translation 3 units down, which is a sequence of rigid motions.

<h3>Answer: 2880 pounds per square foot</h3>
==========================================================
Explanation:
psi = pounds per square inch
1 foot = 12 inches
1 square foot = 144 square inches
I squared both sides to get the second equation. Think of a 12 by 12 square representing 12 inches along each side, so that leads to 12*12 = 144 square inches being the same as 1 square foot.
That last equation helps us convert from square inches to square feet like so:
Notice in the jump from the second step to the third step, we have the "square inches" unit cancel out when dividing. All that's left is "pounds" up top and "square foot" down below.
In short, we simply multiply by 144 to go from 20 to 2880.
