Question

In the given figure find the measure of angle 1 angle 2 angle 3 if angle 4 =140°

Answer 1

Step-by-step explanation:

condition 1st : if figure is rombus

then all angles of squre arual

i.e angle 1 = angle 2 = angle 3 = angle 4

then if angle 4b= 140 then

angle 1 , angle 2 and angle 3 = 140

condition 2nd : if figures is parallelogram

then opposite angles are equal

ie ange 1 = angle 3 and angle 2 = angle 4

also sum of all angles are 360

ie. angle 1 + angle 2 + angle 3 + angle 4 = 360

so let let angle 1 be x

then x + x + 140 + 140 = 360

2x + 280 = 360

2x = 360 - 280

2x = 80

x = 40

angle 1 and angle 3 = 40 also angle 2 and angle 4 = 140
