Measure that angle (Posted on 2002-06-18) Difficulty: 5 of 5
Given that:
  • ABC is an isosceles triangle in which
        AB = AC
  • The lengths of the following segmets are equal:
        AD
        DE
        EC
        BC
    Find the measure of angle A.

    sum of triangle = 180
    sum of quadrilateral = 360

    angle A=40 degrees
    angle ADE=100 degrees
    angle AED=40 degrees
    angle EDB=80 degrees
    angle DEC=140 degrees
    angle B=70
    angle C=70

    in an isoceles triangle, the base angles are congruent.

    trial and error, it works i guess
