In the paper it is considered a construction of an egg curve
obtained by continual joining of the circular arcs with three different
centers. These three centers form sharp or flat triangles of the
pentagon (sharp and flat triangles are the basic building shapes of
Penrose tiling). They have many relationships with both the Fibonacci numbers and Phi. In such an egg curve, it is possible to inscribe two juxtaposed pentagons. We give also another construction which employs several, even infinite number of the pentagons. Those pentagons are forming a sequence related to Fibonacci sequence. The construction using the flat triangles will provide a curve which ratio between length of the perimeter and the sum of the length of its minor and major axes will give the coefficient Φ.
