A triangle is dilated by a scale factor of One-fifth and then rotated 90 degrees clockwise about the origin. Why is the image similar to the pre-image? Check all that apply. The corresponding sides of the triangles are congruent.
The corresponding angles of the triangles are congruent.
The corresponding sides of the image are 5 times as long as those of the pre-image.
The image is a reduction of the pre-image.
Neither the dilation nor the rotation change the shape of the triangle.
The rotation reduces the size of the triangle.
