15²=12²+x²

x² =15²-12²

x² =225-144

x² = 81

Collect like terms
x + 4x - 4 = 9 - 2 x - 6
move the terms
5x - 4 = 3 - 2x
collect like terms calculate

Triangle DEF is reflected over the y-axis, and then translated down 4 units and right 3 units. Which congruency statement descri

DerKrebs [107]

The point D transformed into S
The point E transformed into R
The point F transformed into U

The lengths are angles didn't change as result of the transformations (rotation and translation do not change the shape nor dimensions). Then, the resulting triangle is congruent to the original triangle.

Using the same order for the letters, you might say that ΔDEF ≅ ΔSRU
