Answer:

the first one as you can see they are the same patterns. eule r circuit starts at the edge and end at same vertex. clue look at the drawing you can find triangles like bcd, b,e d . d,ef.

A Euler Path has 2 odd vertices and the rest are even, an Euler circuit has 2 ODD vertices and the graph number 1 has an Euler circuit.

What is an Euler Circuit?

Euler Circuit is the circuit which utilize each edge of the graph for a single time.

Properties of Euler Circuit;

  • To be an Euler path, for a graph, there must be 2 odd vertices.
  • All the vertices has even vertices.

In the first figure there is an Euler circuit exist as there is the path bcd, bed , def can be seen which connects its path.

Thus, a Euler Path has 2 odd vertices and the rest are even, an Euler circuit has 2 ODD vertices and the graph number 1 has an Euler circuit.
