    Paralleelseteks sirgeteks nimetatakse sirgeid, ....

    • A.

      Mis asetsevad samal tasandil ja millel ei ole ühist punkti.

    • B.

      Millel on üks ühine punkt.

    • C.

      Millel on üks ühine punkt ja mis moodustavad teineteise suhtes täisnurga.

    • D.

      Millel ei ole ühist punkti.

    Correct Answer
    A. Mis asetsevad samal tasandil ja millel ei ole ühist punkti.
    Explanation
    Paralleelseteks sirgeteks nimetatakse sirgeid, mis asetsevad samal tasandil ja millel ei ole ühist punkti. This means that parallel lines are lines that are on the same plane and do not intersect each other.

    Lõikuvateks sirgeteks nimetatakse sirgeid, .....

    • A.

      Mis asetsevad samal tasandil ja millel pole ühtegi ühist punkti.

    • B.

      Millel on üks ühine punkt.

    • C.

      Millel on üks ühine punkt ja mis lõikuvad täisnurga all.

    • D.

      Millel pole ühtegi ühist punkti.

    Correct Answer
    B. Millel on üks ühine punkt.
    Explanation
    Lõikuvateks sirgeteks nimetatakse sirgeid, mis asetsevad samal tasandil ja lõikuvad ühes punktis. See tähendab, et neil on vähemalt üks ühine punkt, kus nad ristuvad.

    Correct Answer
    C. Millel on üks ühine punkt ja mis lõikuvad täisnurga all.
    Explanation
    The correct answer is "millel on üks ühine punkt ja mis lõikuvad täisnurga all." This means that skew lines are lines that have one common point and intersect at a right angle. Skew lines do not lie on the same plane and do not have any other points in common.

    Milline järgmistest lausetest on paralleelide aksioom?

    • A.

      Väljaspool sirget asuvat punkti läbib ainult üks sirge, mis on paralleelne antud sirgega.

    • B.

      Sirged on paralleelsed, kui neil ei ole ühtegi ühist punkti.

    • C.

      Kui kaks sirget on paralleelsed kolmandaga, siis on nad paralleelsed teineteisega

    Correct Answer
    A. Väljaspool sirget asuvat punkti läbib ainult üks sirge, mis on paralleelne antud sirgega.
    Explanation
    The sentence "Väljaspool sirget asuvat punkti läbib ainult üks sirge, mis on paralleelne antud sirgega" states that only one line passes through a point outside the line, and that line is parallel to the given line. This statement aligns with the definition of parallel lines, which are lines that do not intersect and are equidistant at all points. Therefore, this sentence can be considered an axiom or a fundamental truth about parallel lines.
