When Polygon KLMN in the example was translated. How did the angle and line properties changed?Explain.

When two shapes have been translated the angles stay congruent and in symmetry the angles stay the same. The sides only magnify to a larger measure in projection and scale change.

You can also check the rotational fit for both shapes.

If the line appears to be different line after rotation ie) facing east after rotation would be 90 degree rotation if it fits then the angle has not changed for 4 sided shape, for 3 sided this would be 60 degree for equilaterial or a different angle that matches one other angle for isosceles, you can count the vertices and see if rotation fits for the same points rotational points of change.  

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
