True or false: a stop sign hhas both parallel and intersecting line segments.
What is true?
True or false? An angle is formed by only two rays that have the same endpoint.
What is false? An angle can also be formed by line segments that have the same endpoint.
An obtuse angle has this anount of acute angles
What is 2?
