Please help geometry. Thanks if you do!

h=24

Step-by-step explanation: In order to solve this we have to apply the Pythagorean Therom which states a^2+b^2=c^2. c^2 being the the hypotenuse.  First we have to plug in the values so the new equation is a^2+7^2=25^2. Now we simplify to get a^2+49=625. We can now subtract 49 from both sides to get a^2=576. The final step is to square it to get a=24. So h=24

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.
