Question

The vertices of Triangle I are (1, 3), (2, 1) and (5, 0). Triangle I is reflected across the x-axis, resulting in Triangle II. Triangle II is then rotated 180o about the origin, resulting in Triangle III. Draw and label Triangles I, II and III on the same coordinate plane. Describe a single transformation that would map Triangle I directly onto Triangle III.

Answer 1

triangle b is simply obtained by addinq negative to the y coordinate
new points
1,-3
2,-1
5,0
triangle c is obtain by changing the signs to both x and y
so you get
-1,3
-2,1
-5,0
a single trans would be a reflection on the y axis

Answer 2

thats the answer?

Answer 3

Yes, A Single transition would be a reflection on the y axis... All the stuff above is just an explanation/walkthrough
