Rhombus 29

One of the diagonals of a rhombus is equal to a side of the rhombus. Find the angles of the rhombus.

Correct result:

A =  120 °
B =  60 °
C =  120 °
D =  60 °

Solution:

a=u a=b=c=d SSS:a,u,b U=180/3=60  A=2 U=2 60=120a=u \ \\ a=b=c=d \ \\ SSS: a, u, b \ \\ U=180/3=60 \ ^\circ \ \\ A=2 \cdot \ U=2 \cdot \ 60=120 ^\circ
