    at 4:36 there is a mistake that complete graph is not bipartite but in case of connected it may or may not be.
    Thank You for teaching.

    Bhot Bhot Thank You!
    Mai aapka channel to sbko recommend krta hu par kisiko aapka content accha ni lagta kyonki wo kehte hai aap bhot tez padhate ho jabki unke khud k basics strong nahi.
    Par Jo bhi hai sir aap best ho. Kyonki no. To zyada aapke hi students k aate hai

    🎯 Key Takeaways for quick navigation:
    00:43 🌐 *Complete graphs connect every vertex to every other, forming a fully interconnected set.*
    01:27 🔄 *Regular graphs have vertices with equal degrees, indicating the same number of connected edges.*
    02:10 🔗 *Bipartite graphs split vertices into two sets, connecting edges only between vertices in different sets.*
    03:08 🤔 *Connected vertices create sets, and disjoint sets signify partitions.*
    03:51 🧩 *Graphs with disjoint sets for vertices and edges are termed bipartite.*
    04:18 🤝 *Connected graphs require a path between any pair of vertices.*
    05:01 🌐 *Connected graphs cannot be bipartite, and bipartite graphs lack interconnected paths.*
    05:42 🔄 *Complete bipartite graphs connect every vertex in one set to every vertex in another.*
    05:57 🔄 *A complete bipartite graph (k22) comprises two disjoint sets with interconnected vertices.*
    06:25 🚫 *In a complete bipartite graph, each vertex connects to every vertex in the other set.*
    07:32 🔄 *A subgraph (G') of graph G is a subset obtained by removing some vertices and edges.*
    08:13 🚧 *Graph decomposition involves breaking it into parts and recombining through operations like union and intersection.*
    08:43 🔄 *Union of disjoint graphs results in the entire graph, while intersection retains common vertices, forming a null graph.*
    08:56 📚 *The concept of "complement" in graph theory connects non-connected vertices in a graph.*
    10:12 🔄 *Planar graphs have non-intersecting edges, forming a graph when edges do not cross.*
    10:56 📐 *Rearranging intersecting edges creates a planar representation of a graph.*
    11:38 🧩 *A complete graph involves two vertex sets, each connected to every vertex in the other set.*
    12:05 🔄 *In a complete graph, every vertex connects to every other, forming a set of edges.*
    13:01 🔄 *A regular graph has every vertex with the same degree, indicating an equal number of connected edges.*
    13:29 🔄 *Bipartite graphs split vertices into two sets, with edges connecting vertices from different sets.*
    14:29 🔄 *The Handshaking Theorem states that the sum of degrees of all vertices equals twice the number of edges.*
    15:07 🔄 *The Handshaking Theorem states that the sum of degrees of all vertices equals twice the number of edges.*
    15:21 🔄 *Doubling the number of edges in a graph equals the sum of the degree sequence of the vertices.*
    I hope this will help others.

    Sir, there's a note in your video "If a graph is connected then it will not be bipartite" and you are reading it again and again means you are not makin any mistake as you are so confident on this statement. I think you should check this.

    going by the definition of connected graph , it should be able to be bipartited in some cases . Although a complete graph will never be bipartited.

      But a connected graph has a connection between every two vertices. And the complete graph is a graph where all the vertices are connected. I think both are meaning the same thing .

    01:52 Regular Graphs and Bipartite Graphs
    03:40 The graph discussed is a bigraph with two disjoint sets.
    05:18 A bipartite graph is a graph that can be divided into two sets with no edges within the sets.
    07:18 Graph theory includes the concepts of subgraph and decomposition of graphs.
    08:54 A planar graph is a graph that can be drawn in a plane without any edges crossing.
    10:50 Types of Graph: Bigraph, Regular Graph, Complete Graph
    12:24 Graph types: Complete graph, Regular graph, Bi-parted graph.
    13:57 Graphs can be connected or bi-parted

      Consider X,Y,Z Vertices and take that X has a edge with both Y and Z then Set 1 = {X} which connects other two Vertices and Set 2 = {Y, Z} Vertices which are connected by X.
      In Complete Bipartite - Just like Above, Consider You have Set 1 = A and Set 2 = B then All Vertices of Set B are to be connected with Set A's each Vertice.

      Therefor every complete graph is connected graph but vice versa is not true.

      All regular graphs are not complete graphs but all complete graphs are regular graphs.
      Regular graphs means every vertices will have the same degree whereas complete graph will have every vertices as its adjacent vertice which will have the same degree only and will make it a regular graph.
