Repasa los Apuntes de matemáticas de la lección 8.2.2 para ayudarte a determinar la suma de los ángulos interiores de un polígono.

  1. An equilateral triangle with angles labeled x.

  1. A polygon with angles 130 degrees, 46 degrees, x and 102 degrees in that order clockwise.

  1. A polygon with angles 10 x, 8 x minus 16 degrees, 12 x minus 8 degrees, 7 x plus 2 degrees, 9 x plus 4 degrees and 6 x plus 10 degrees in that order clockwise.

  1. Two increasing parallel lines with a horizontal transversal. Angle x is the upper, exterior, angle about the left parallel line and the transversal. A pentagon is formed with line segments of the bottom, right parallel line and the right end of the transversal along with three other line segments. The angles from the end of the transversal, clockwise about the pentagon is 123, 90, 97, and 113 degrees.  The lower exterior angle between the transversal and the right parallel line is unknown.

    ¿Cómo se relacionan y el ángulo faltante del polígono?
