Question

Given parallelogram ROCK and KR = 57, RO = 3, find CK.
R
K

Answer 1

Answer: The length of CK = 3 units.

Explanation:

Given parallelogram ROCK and KR = 57 units , RO = 3 units

A parallelogram is a kind of quadrilateral with following characteristics:

• The opposite sides are parallel.
• The opposite sides are congruent (i.e equal) .
• The opposite angles are congruent.
• The diagonals of parallelogram bisects each other.

So , if ROCK is a parallelogram, then

RO = CK [Opposite sides are congruent]

i..e CK = RO= 3 units

That means , the length of CK = 3 units.
