Question


The points in the figure shown lie in the same plane. If triangleABF is congruent to triangleEDG, where angleA corresponds to angleE and angleB corresponds to angleD, what is the measure, in degrees, of angleGCF? (Disregard the degree symbol when gridding your answer.

The correct answer is: 100


    increment A B F & increment E D G are congruent.

    angle A equals angle E equals 65 degree

    angle B equals angle D equals 75 to the power of degree

    angle G equals angle F equals 40 degree

    In capital delta G C F space angle G plus angle C plus angle F equals 180 degree

    40 plus x plus 40 equals 180 degree
    x equals 180 minus 80 equals 100 degree
