Question

In the rhombus :Angle 1 = 140 What are Angle 2 and Angle 3? The diagram is not to scale.

A. Angle 2 = 40 and Angle 3 = 70
B. Angle 2 = 140 and Angle 3 = 20
C. Angle 2 = 40 and Angle 3 = 20
D. Angle 2 = 140 and Angle 3 = 70

Answer 1

you know all the angles amount to 360 degrees in the rhombus. I will give you one more clue: Opposite angles are equal so:
Angle 1=Angle 2 and Angle 3=Angle 4 (which is not drawn)

Then, angle 2= angle 1=140,
If angle 1=angle 2= 140, how much is angle 1+angle 2
60 and 80 which equals 140

That's because angle 3 is half of 40 (it's 20). Notice the line going through the middle of the shape, the angle labeled 3 is only talking about half of the full corners angle, it's only asking for the bottom half of that angle.
