Question

The ratio of adjacent angles of parallelogram is 1:1 . The special name of the parallelogram

Answer 1

Answer:

The ratio of adjacent angles of a parallelogram are 1:2

⇒ Let the adjacent angles are x and 2x

We know, that sum of the adjacent angles of parallelogram is 180

o

∴ x+2x=180

o

⇒ 3x=180

o

⇒ x=60

o

Adjacent angles are,

⇒ x=60

o

⇒ 2x=2×60

o

=120

o

∴ The smallest angle is 60
