Triangle ABC is transformed to form triangle A'B'C' . A is at (3, 1) , B is at (1, 8) , and C is at (7, 2) . Which transformatio
n happened to △ABC to form △A'B'C' ? Drag and drop the the correct answers into the each box to complete the sentence. △ABC is to form △A'B'C' . A graph with a triangle on it formed between points A begin ordered pair negative 3 comma negative 1 end ordered pair, B begin ordered pair negaive 1 comma negative 8 end ordered pair, and C begin ordered pair negative 7 comma negative 2 end ordered pair.
Both the x- and y-values of each point are negated.
A reflection across the x-axis will negate the y-coordinate; a reflection across the y-axis will negate the x-coordinate. Both in one transformation is the same as reflecting across the line y=x.
