Answer:
Arc AB is a semicircle, Not true.
Step-by-step explanation:
In circle O, central angle AOB has measure of 90°
We need to choose statement which is not true. We can see the attachment to shape of circle.
As we can see O is the center of circle. A and B are two points on circle.
So, OA and OB must be radius of this circle.
1) Segment OA is a radius ( TRUE )
2) Segment OA and OB are perpendicular (TRUE)
Because central angle makes 90°
3) arc AB is a semicircle (FALSE)
Because AOB is not 180°
