Question

Millie is using a software program that allows her to change the shape of a two-dimensional figure by making changes to the angles at vertices. She starts with a quadrilateral with all four angles congruent. She moves the vertices to make two pairs of congruent angles.

Which statement best describes the figure that she created?

She changed a rectangle to parallelogram.

She changed a rhombus to a kite.

She changed a rectangle to a trapezoid.

She changed a rhombus to a parallelogram.

Answer 1

If the 4 angles of a quadrilateral are congruent, and a quadrilateral's angles add up to 360, what type of angles are they?

Answer 2

right

Answer 3

Ok. What type of quadrilateral has all right angles? Rhombus, parallelogram, or rectangle?

Answer 4

rectangle

Answer 5

Alright. The original figure was a rectangle. That narrows it down to A or C. A parallelogram has opposite angles congruent, so that would mean that it has 2 pairs congruent. That means that it would be A. :)

Answer 6

could it be a trapizoid

Answer 7

No. A trapezoid doesn't have to have any angles congruent. The only way it would be a trapezoid is if it said isosceles trapezoid.

Answer 8

thanks

Answer 9

np :)
