We know opposite angles in the parallelogram is congruent:
let x to be the unknown angle:
360=2(110)+2x
360=220+2x
140=2x
x=70
ECF is also 110 because of parallel lines and corresponding angles:
110+x+y=180
110+30+y=180
y=40
so DAE is 40
Answer:
(a) A and B are similar but not congruent
Step-by-step explanation:
All of the rectangles have sides in the ratio of 2:1, so are all similar. Only the rectangles that are the same size are congruent: A and C.
A and B are similar, but not congruent.
