Question

One of the diagonals of a rhombus and its sides are equal. Find the angles of the rhombus.

.​

Answer 1

Answer:

60 degree and 120 degree

Step-by-step explanation:

Suppose rhombus ABCD

AC be one diagonal

Triangle ABC has equal sides which is equilateral triangle

Therefore angle B and angle D=60 degree

Therefore Angle A= angle C

Therefore angle A= (360-60+60)/2 =(360-120)/2

=240/2

=120

Therefore angle A and angle C = 120 degree

Answer 2

Answer:

60 degree and 120 degree

Step-by-step explanation:

dekho 1 diagonal aur charo side equal h

suppose abcd is a rhombus , in which ab=bc=cd=da=ac

then, in triangle abc, ab=bc=ac

thus its all angle willbe 60 deg.

ab dekho, angle a+angle b=180 deg.

and we have angle a/2 or angle bac 60 deg. h isliye ang. dac=60

hence ang. a =120 and ang.b=60 deg.

hope you may understand.
