Question

Triangle A is rotated 180° counterclockwise about the origin. Which figure is the transformed figure?

Answer 1

the first triangle shows what it’s starting at.

the first transformation is turn 90 degrees clockwise.

the second transformation is turned ANOTHER 90 degrees, which would make the total transformation 180 degrees

Explanation:

Answer 2

It is given that Triangle A is rotated 180° counterclockwise about the origin.As there are four Quadrants ,If Triangle is in odd Quadrant it goes into Odd Quadrant after rotation of 180 degree, and if Triangle is in even Quadrant, then Triangle shifts in even Quadrant after rotation of 180 degree.

When among the four transformation

Rotation takes place, The preimage and Image are Congruent.That is Neither Side Length , Nor Interior Angles of Two triangles Changes.

So,The transformed Figure will also be a Triangle congruent to Original Triangle which was rotated by an Angle of 180°.
