Ava draws three parallelograms. in each figure, she measures a pair of angles, as shown.

what is a reasonable conjecture for ava to make by recognizing a pattern and using inductive reasoning?

in a parallelogram, all angles are congruent.

in a parallelogram, opposite angles are congruent.

in a parallelogram, opposite angles are acute.

in a parallelogram, all angles are acute

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
