1. A panel, in particular a floor panel, interconnectable with similar panels for forming a covering, comprising:

  • a centrally located core provided with an upper side and a lower side, said core being provided with;

    a first pair of opposite edges, comprising;

    a first edge comprising a sideward tongue extending in a direction substantially parallel to the upper side of the panel, a bottom back region of said tongue being configured as a bearing region, wherein the bottom back region is located closer to the level of the upper side of the panel than a lowest part of a bottom front region,an opposite, second edge comprising a recess for accommodating at least a part of the sideward tongue of a second panel, said recess being defined by an upper lip and a lower lip, said lower lip being provided with an upwardly protruding shoulder facing the bearing region of the sideward tongue,the sideward tongue being designed such that locking takes place by an introduction movement into the recess of a sideward tongue of the second panel and an angling down movement about an axis parallel to the first edge, as a result of which a top side of the sideward tongue will engage the upper lip and the bearing region of the sideward tongue will be supported by and/or facing the shoulder of the lower lip, leading to locking of the panel and the second panel at the first and second edges in both a horizontal direction and a vertical direction; and

    a second pair of opposite edges, comprising;

    a third edge comprising a single upward tongue, at least one upward flank lying at a distance from the upward tongue and a single upward groove formed between the upward tongue and the upward flank, and wherein at least a part of a side of the upward tongue facing away from the upward flank comprises a substantially rigid first locking element, anda fourth edge comprising a single downward tongue, at least one downward flank lying at a distance from the downward tongue, and a single downward groove formed between the downward tongue and the downward flank, and wherein the downward flank comprises a substantially rigid, second locking element adapted for co-action with a first rigid locking element of a third edge of a third panel,the third and fourth edges being designed such that locking takes place during angling down of the second panel at a first edge of the second panel to a second edge of the panel, wherein the fourth edge of the second panel makes a scissoring movement toward the third edge of the third panel, such that the downward tongue of the fourth edge of the second panel will be forced into the upward groove of the third edge of the third panel and the upward tongue of the third panel will be forced into the downward groove of the second panel, by deformation of the third edge and/or the fourth edge, leading to locking of adjacent panels at the third and fourth edges in both the horizontal direction and the vertical direction,wherein at least a part of a side of the upward tongue facing toward the upward flank is inclined toward the upward flank and extends in the direction of the normal of the upper side of the core, andwherein at least a part of a side of the downward tongue facing toward the downward flank is inclined toward the downward flank and extends in the direction of the normal of the lower side of the core.
