• 交わるまじわるJLPT N1approx.Common

  These lines meet at right angles.
• 接続せつぞくJLPT N2approx.Common
  noun, suru verb, transitive verb, intransitive verbThe noun for join: a connection, attachment, or union between things. Use it when English needs join as a noun — the link itself — rather than as a verb for the act of joining.
