Question

construct a quadrilateral ABCD ,ab=bc=cd=da,angleA is =120, what type of qurdirlateral is it

Answer 1

Answer: rhombus

Step-by-step explanation:all the sides of a rhombus are equal and the diagonals bisect easy other and are perpendicular so sum of the opposite andles will always be equal to 180 so angle A + angle B=180

120+angle B=180

Angle B = 60
