Question

In a rhombus ABCD, AC = AD. Find the measurements of <B and <DCB.

Answer 1

since ABCD is a rhombus then a b = 2 BC = 2 CD = today but from the question is equals to add their for AC equals to BC equals to CD ABC is isosceles triangle their full angle abc b c d and b s equals to 60 degree ice in same angle equal triangle DS equal Triangles a CD there for the measurement of Angle B and angle DCB equals to 60 degree
