Question

Find measure of angle ECD , if AB is parallel to DE. Also state which two sides of triangle

CED are equal and why?​

Answer 1

Answer:

74

AB parallel to DE. <A =<CED (alternate angles)

< D +<CED + <DCE =180( Angle sum property of triangle)

53+53+<DCE= 180

<DCE= 180-106

<DCE= 74

CE=CD( Since, both the angles are equal, it is an isosceles triangle)
