Determining obtuse vertical angles

The video tutorial explains the concept of vertical angles, focusing on acute and obtuse angles. It discusses how to identify vertices and the properties of vertical angles, emphasizing that obtuse angles are larger than 90 degrees. The tutorial also covers how intersecting lines create vertical angles and concludes with a recap of the key points discussed.

What is a key characteristic of an obtuse angle?

• It is a right angle.

• It is greater than 90 degrees.

• It is exactly 90 degrees.

• It is less than 90 degrees.

Which of the following is true about vertical angles?

• They are always acute.

• They share a vertex but have no common sides.

• They share a common side.

• They are always right angles.

What is the significance of intersecting lines in the context of vertical angles?

• They create parallel angles.

• They create acute angles.

• They create vertical angles.

• They create right angles.

What is the relationship between angles BFD and CFG?

• They are vertical angles.

• They are supplementary angles.

• They are complementary angles.

• They are adjacent angles.
