Answer 1

Answer:

ABCD is a square and BCE is an equilateral triangle . Find the measure of each of the angle a,b,c,d,e,f,g .

Answer 2

Answer:

ABCD is a square and BCE is an equilateral triangle. The angle DCE = 90 + 60 or 150 degrees. Since BCE is an equilateral triangle, CE = CB = CD, so DEC is an isosceles triangle. So angle DEC = angle

EDC = (180 - 150)/2 = 30/2 = 15 degrees.
