In a parallelogram A B C D ,\ /D=135^0, ...

In a parallelogram `A B C D ,\ /_D=135^0,` determine the measure of `/_A\ a n d\ /_Bdot`

Text Solution

Verified by Experts

Given that
In a parallelogram `ABCD `
`angleD= 135^0`
` angleC + angleD = 180^0..` (supplementary angles)
` angleC = 180^0 - 135^0`
`angleC= 45^0`
`angle C = angleA `and `angleD = angleB `(Opposite angles of parallelogram)
`angleA = 45^0`
` angleB = 135^0`
