The coordinates of the vertices of △RST are R(−3, −1) , S(−1, −1) , and T(−4, −5) .

The coordinates of the vertices of △R′S′T′ are R′(1, −2) , S′(1, 0) , and T′(5, −3) .

What is the sequence of transformations that maps △RST to △R′S′T′?

Drag and drop the answers into the boxes to correctly complete the statement.

Question:

A sequence of transformations that maps △RST to △R′S′T′ is..... followed by..... .

rotation of 180° about the origin

reflection across the y-axis

a translation 1 unit up

a rotation of 90° counterclockwise about the origin

rotation of 90° counterclockwise about the origin   ( a, b)  →  (-b. a)

translation of 1 unit up   (-b, a) → (-b, a + 1)

Example

R = (-3,-1)

First transformation yields ( 1, -3)

Second  transformation  = (1, -2)  = R'

And so  forth  ( check the other points for yourself)

CPhill, did you happen to notice the title of the question? That's a very big red flag, best to leave this question unanswered.
