all sides are congruent in quadrilateral abcd below how would this quadrilateral be best classified and what is the measure of <b

It is a rhombus. All sides are equal. No right angles consecutive angles are supplementary. 180 - 110 = 70
Answer: C and <B = 70 degrees.
Note: A kite has two sets of two equal sides in each of the two sets, not all 4 sides being equal. Each member of the set is equal to the other member of the set, but the sets do not have members of a set equal to members of the other set.
Answer:
The third option (rhombus; mB=70 degrees
Step-by-step explanation:
The shape is not a kite, so you can eliminate the first two options out of the answers to make it easier for you to solve. As you can see, angle A is the same as angle C, meaning they are both 110 degrees. And we can observe that angles D and B are smaller than A and C, meaning it must be the third option. (Also, I took the quiz and got it right).
