Question

△QRS is rotated about point P to △Q′R′S′ .

Answer 1

A rotation is a transformation that preserves figure shape, figure sizes, angles and lengths.

Therefore,

• option A is false, because rotation preserves sizes;
• option B is false, because rotation doesn't change the figure size;
• option C is true, because rotation preserves figure angles;
• option D is true, because rotation preserves lenghts of segments.

Answer: option C and D.
