If one of the diagonal of a rhombus is equal to its sides find all angles of the
rhombus.
Answers
Answer:
180°
Step-by-step explanation:
If we have the rhombus as one side is equal to the diagonal then we have the rhombus divided into two equilateral triangles. So, other angles are equal as that is a rhombus and two adjacent angles will give us sum as 180∘ .
Hey guys it will help you.
ABCD is A rhombus which means
AC= BC .....i
BC= AB......ii
from equation i and ii
AC=BC=AB
Triangle ABC is an euilateral triangle
so angle ABC = 60°
angle BCA = 60° ......iii
angle CAB= 60° ......iv
Similarly in triangle ADC
AD = DC ( sides of a rhombus)
AD = BC
but BC = AC
AD = AC
AD = DC = AC
Triangle DAC is an euilateral triangle
angle A = 60° ......v
angle D = 60°
angle C = 60° .......vi
from equation iii and vi we get
angle BCA + angle DCA = 60 + 60 = 120°
angle A = 120 °
Hence the angles of a rhombus are
120° , 60° , 120° , 60°
