Triangles abc and def. coordinates for a are negative 1, negative 1, for b 2, 4, and for c 3, 1. given: δabc ≅ δfde what is the length of segment line de rounded to the nearest tenth? 3.2 4.2 2.2 3.6

We have been given that triangles abc and fde are congruent. Therefore, the corresponding sides must be equal too. Using this fact, we can write:

ab = fd, bc = de and ca = ef

We are given the coordinates of vertices of triangle abc as:

a(-1,-1), b(2,4) and c(3,1).

Since line segment de is equivalent to line segment bc. Therefore, we can write

Therefore, the first choice is the correct answer.

2 2/3 hours duhh silly
