I need to know what statements are true but I’m having a hard time choosing. I need guidance

Given
[tex]\Delta A^{\prime}B^{\prime}C^{\prime}\text{ is formed by dilating }\Delta ABC[/tex]Find
Which statements are true?
Explanation
As we know the properties of dilation ,
1 . each angle of the figure is same.
2. parallel and perpendicular lines (Perpendicular lines is defined as a straight line that makes the right angle with other line) in the figure remain the same as the parallel and perpendicular lines of the dilated figure.
3 . length of the sides of the original image and the dilated image may vary.
therefore , options A , B and D are true.
Final Answer
Therefore , the correct options are A , B and D.
