Question

18. Identify a sequence of transformations that maps triangle ABC onto triangle A′′B′′C′′ in the image below.

(1 point)
clockwise 90° rotation; enlargement
counterclockwise 90° rotation; reduction
counterclockwise 90° rotation; enlargement .......
clockwise 90° rotation; reduction

Can someone tell me if im correct please?? only if you taken the test you will know but if you have tell me if im correct and I really think the answer is c im pretty positive it is...

Answer 1

Since we have no image, we cannot help. Why don't you try cutting out a triangle of the appropriate size, and see what you have to do to get it to line up with the other.

If there's a scaling factor, make sure that you don't move the center of the triangle, and move it till all three vertices line up with the image.

On the other hand, a 90° counterclockwise rotation takes (x,y) -> (-y,x)
