Triangle ABC is translated one unit right into units down. What are the coordinates of the translated triangle
Do you use arrow notation to write a rule for this translation
To find the new coordinates of the translated triangle, we simply add 1 to the x-coordinate and subtract 2 from the y-coordinate of each vertex.
So if the original vertices of triangle ABC were A( x1, y1), B(x2, y2), and C(x3, y3), then the new vertices after translation would be:
A'( x1+1, y1-2), B'(x2+1, y2-2), and C'(x3+1, y3-2)
We can write the rule for this translation as:
(x,y) -> (x+1, y-2)
This means that any point (x,y) is transformed into a new point (x+1, y-2) after the translation.
