Please help.

Is each biconditional statement true or false?



Select True or False for each statement.

True or False: An angle is a right angle if and only if the measure of the angle is 90°

Truth or false: An angle measures 120° if and only if the angle is an obtuse angle.

True or False: An angle measures 180° if and only if the angle is a straight angle.

Answer 1

The 1st is true
Because the statement ang angle is right if and only if it's measuw is 90
And the converse of that is is the measure of an angle is 90 then the angle is only right that's also correct.. So true

Answer 2

and the other two?

Answer 3

The 2nd is false because the statement
An angle measure 120 if and only if it is obtuse well that's true but the converse is
If the angle is obtuse then it is only measures 120 degrees. That's incorrect because obtuse is all angles above 90

Answer 4

The 3rd is true Because the statement
An angle measure 180 if and only if it is a straight line that's correct
The converse is
If it is a straight line then the measure is only 180 degrees that's also correct so yeah correct
