[24 points] We wish to investigate a new type of relation which we will call Vahidean. A relation R on the set A is Vahidean if: ∀a, b, c ∈ A aRb ∧ aRc → bRc a) Explain, in English, how Transitivity and Vahideanness are different. Give an example of a Vahidean relation on {a, b, c, d} which is not transitive (draw its digraph representation). Give a counterexample that shows your relation is not transitive. b) Is the following an implication of Vahideanness? ∀a, b, c ∈ A aRb ∧ aRc → cRb Explain why or why not. c) Prove that if a relation R is Reflexive and Vahidean then R is an equivalence relation.

i believe that the slope of the line is -5

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
