In RT △ ABC, ∠ C is equal to 90 degree CD.CE If ∠ A is equal to 30 °, try to judge the shape of ∠ BCE Geometric steps, is an equilateral triangle

In RT △ ABC, ∠ C is equal to 90 degree CD.CE If ∠ A is equal to 30 °, try to judge the shape of ∠ BCE Geometric steps, is an equilateral triangle

(a is 30 degrees, then (B is 60 degrees, CE is the middle line on the side AB, be equals AB and BC {the right side opposite the 30 degree angle is half of the hypotenuse}, so the triangle BCE is an equilateral triangle, then (BCE equals 60 degrees
