Sagot :
The rotation of the triangle that's illustrated will be a rotation of 90°.
How to illustrate the information?
It should be noted that transformation is a general term for 4 specific ways that can be used to manipulate the shape and the position of a point, line, or a geometric figure. In such a case, the original shape of the object is called the pre-Image while the final shape and the position of the object is simply the image under transformation.
There are typically four common types of transformations and they're translation, rotation, reflection, as well as dilation. It should be noted that rotation about simply illustrates the transformation that takes place regarding the triangle.
For rotation, the shape rotates or turns the pre-image around the axis and there'll be no change in the size or shape of the object.
Here, the counterclockwise rotation was illustrated in the triangle ABC. Therefore, the rotation of the triangle that's illustrated will be a rotation of 90°.
In conclusion, based on the information given, the correct option is A.
