Let's do this question, one of the diagnose of a rhombus and its sites are equal.
Find the angles of the rhombus.
All right, pause the video, give it a try, and then let's do it together.
All right.
We're back.
I hope you have given it a try.
Let's do it together.
Over here.
You have Rhombus ABCDE.
Let's construct its diagonals.
That's beauty and AC let the length of the side of the rhombus be of eight centimeters.
All right.
Now, let's say beauty is equal to it because it's given that one of the diagonals of the rhombus is
equal to the side.
All right.
Now let's mark these angles over here as angle one angle to angle three and angle for now.
Consider a triangle a beauty.
Right now you can see that abs of lengthy it is of length and beauty is also of length.
So Triangle Abady is an equilateral triangle, right?
Therefore, angle is equal to sixty degrees and angle one and angle two also is equal to sixty degrees.
Right.
Similarly you will see that triangle CBD is also an equilateral triangle and hence angle three equals
angle four is equal to sixty degrees and angle is also includes sixty degrees.
Now therefore the angles of the rhombus.
That's what we have to find out is 60, 60 and 120 and 120 degree right.
Angle A 60 angle C 60 and angle BS angle one plus angle three, angle one is sixty and angle three sixty
two.
Angle B is 120 degrees.
Similarly Angle D is also equal to 120 degrees.
