Question

TriangIe BCD is rotated 180 degrees clockwise and then dilated by a factor of 4 centered at the origin. The resulting image is trinagle BCD. Which statement about the two triangles is true

Answer 1

Answer:

pls mark me as brainliest if you are satisfied

Step-by-step explanation:

Answer:

B) The perimeter of ABCD is 4 times the perimeter of A'B'C'D'.

D) The corresponding angles of ABCD and A'B'C'D' are congruent.​

Step-by-step explanation:

If triangle BCD is rotated 180° clockwise and then dilated by a factor of 4 centered at the origin;

The area of ABCD is  16 (NOT 4 ) times the area of A'B'C'D'.

B) The perimeter of ABCD is 4 times the perimeter of AB'C'D'.

The corresponding sides of ABCD and A'B'C'D' are in the same proportion and are NOT congruent because dilation is not a rigid transformation.

D) The corresponding angles of ABCD and A'B'C'D' are congruent because the two shapes are similar.
