Which transformations will preserve the parallel and perpendicular lines in the rectangle?

Explanations:
• Take note that the sides of a rectangle are parallel
• All 4 angles are 90 degrees, when they intercept they form a perpendicular line .
• The reflection, rotation and the transformation, will still maintain and preserve the properties of rectangle,
,• opposite side are still going to be parallel and congruent,
90 degrees angles will still remain the same .
This shows that the properties of a rectangle are maintained
