Question

2. Explain whether the following statement is a valid definition: “A 150° angle is an obtuse angle.” Use the converse, biconditional, and at least one Euler diagram to support your answer.

Answer 1

i got converse

Answer 2

It isn't a definition at all.
If an angle measures 150, then it is an obtuse angle.

If an angle is obtuse, then the angle measures 150.........false

A definition is a good definition if its converse is true too.

Euler diagrams are Circles.
Draw a rectangle labled all angles.
Inside the rectangle draw 2 circles that do not touch or overlap.
Lable one circle acute, the other obtuse, put a tiny circle
touching each big circle without overlapping labeled right angles.
In the big acute circle throw in some numbers less than 90
(acute are all angles measuring < 90)
In the big obtuse circle through in some numbers more than 90
be sure 150 is one of the angles.
(obtuse are all angles measuring > 90)
