Question

1. AB and CD are two parallel lines
b. If h = 80°, find d and c.
​

Answer 1

→ d = h = 80° (because corresponding angles)

→ c = 180° - d = 100° (because linear pair)

Answer 2

Answer:

c=100

d=80

Step-by-step explanation:

if h=80 then e+h=180(because of straight angle) so 80+h=180   h=180-80=100

therefore e=100 and d and e are co-interior angles so their sum will be 180 so d=180-100=80 therefore d=80 and c and d are straight angles so c=180-80 which is 100
