As shown in the figure, in square ABCD, ∠ DAF = 25 °, AF intersects diagonal BD at e, intersects CD at F, then ∠ bec=______ Degree

As shown in the figure, in square ABCD, ∠ DAF = 25 °, AF intersects diagonal BD at e, intersects CD at F, then ∠ bec=______ Degree

In the square ABCD, because BD is the vertical bisector of AC, and E is the upper point of BD, EA = EC, ∧ EAO = ∠ Eco, and ∧ Dao = ∠ DCO, ∧ DCE = ∠ DAF ∧ DCB = 90 °, ∧ ECB = 90 ° - 25 ° = 65 °. ∧ BEC = 180 ° - ECB - ∠ EBC = 1
