Answer:

√-1 or i

Step-by-step explanation:

Since A² = 0 we need to get the value of λ when A = 0:

A = λ*λ - 1(-1) = λ² + 1
A = 0
λ² + 1 = 0 ⇒ λ² = -1 ⇒ λ = √-1 ⇒ λ = i

Proof -

A Trapezoid has exactly one pair of parallel sides.

A Kite must have two pairs of adjacent sides congruent.

A Square, Rhombus must have all congruent sides.

Reason -

A trapezoid is a quadrilateral with exactly one pair of parallel sides.

A kite is a quadrilateral with exactly two pairs of adjacent congruent sides.
