Question

If avb has a measure of 80 degree and vm is its angle bisector, what is the measure of avm?

Answer 1

`40\\` degree

Explanation:

VM bisects the angle AVB into two parts i.e angle AVM and VMB

Thus, angle AVM will be equal to half of angle AVB

`= (1)/(2) * 80\\= 40\\` degree

Answer 2

If VM is the angle bisector of ∠AVB then:
∠AVM = 80° : 2
∠AVM = 40°
