As shown in the figure, in diamond ABCD, e and F are the points on BC and CD respectively, ∠ B = ∠ EAF = 60 ° and ∠ BAE = 20 ° to find the degree of ∠ CEF

As shown in the figure, in diamond ABCD, e and F are the points on BC and CD respectively, ∠ B = ∠ EAF = 60 ° and ∠ BAE = 20 ° to find the degree of ∠ CEF

As shown in the figure, connect AC. in diamond ABCD, ab = BC, ∵ ∠ B = 60 ° and ∵ △ ABC is equilateral triangle, ∵ AB = AC, ∵ BAE + ∠ CAE = ∠ BAC = 60 ° and ∵ CAF + ∠ EAC = ∠ EAF = 60 ° and ∵ BAE = ∠ caf, ∵ B = ∠ ACF = 60 ° in △ Abe and △ ACF, ∵ B = ∠ acfab = AC ∠ BAE
