all kites have one set of congruent sides

Question

 All kites have one set of congruent sides

 

Answer 1

Yes. In fact, a kite is defined as a quadrilateral having two pairs of congruent adjacent sides, in other words, two isosceles triangles sharing a common base, but those two triangles not congruent. (If they were congruent, this would be a rhombus.)

 

Note that my answer is yes, because one set of congruent sides is true. The question would have been expressed better by using the phrase "one pair" instead of "one set" because of the ambiguity of the # of elements in an unknown set.

 

"Only one pair of congruent sides" is not true for a kite.
