Question

Figure A and figure B are similar right triangles.

Which series of transformations could have been applied to Figure A to create Figure B?

A dilated 150% then reflected across the x-axis

B dilated 250% then reflected across the y-axis

C dilated 250% then rotated 270 degrees clockwise about the origin

D dilated 500% then rotated 90 degrees counterclockwise about the origin

Answer 1

Answer:

Step-by-step explanation:

The legs of A seem to be about 2 and slightly less than 2 units in length.

The legs of B seem to be about 4.5 and 4.5 units in length

4.5/2 = 2.25 or 225% increase so NONE OF THE ABOVE answer is correct.

If we ASSUME that the legs of B are supposed to reach 5 and 5 (they don't) or the legs of A are both supposed to be 1.8 (hard to say, certainly the bottom one seems to exceed that)

then the dilation would be  5 / 2 = 2.50 or 250%

Which means we have an option of B) or C) to choose from

Reflecting A across the y axis would put B in the first quadrant so NO.

Rotating A  270° CW about the origin would give us B in the third quadrant which is correct.

So the CLOSEST answer is option C) (dilation not with standing)
