1 Answer

  • Answer:

    The measure of an interior angle in a regular triangle is 60 degrees

    Step-by-step explanation:

    we know that

    A regular triangle has three equal sides and three equal interior angles

    Remember that the sum of the interior angles in a triangle must be equal to 180 degrees

    so

    Divide 180 by 3 to determine the measure of each interior angle

    [tex]\frac{180^o}{3}=60^o[/tex]

    A regular triangle is called equilateral triangle

    therefore

    The measure of an interior angle in a regular triangle is 60 degrees
