Angles in the Same Segment

This video tutorial introduces the theorem of angles in the same segment, explaining how angles subtended by the same arc at the circumference of a circle are equal. The lesson revisits the angle at the center theorem and demonstrates the application of the new theorem through various examples. The video emphasizes the importance of identifying segments and chords in a circle and provides practice problems to reinforce understanding. The tutorial concludes with a summary of key points and encourages viewers to subscribe for more content.

What is the main focus of the lesson introduced in the video?

• Angles in a triangle

• Angles at the center

• Angles in different segments

• Angles in the same segment

According to the angle at the center theorem, if the angle at the center is 60°, what is the angle at the circumference?

• 120°

• 60°

• 90°

• 30°

What is the relationship between the angle at the center and the angle at the circumference?

• The angle at the center is twice the angle at the circumference

• The angle at the center is equal to the angle at the circumference

• The angle at the center is three times the angle at the circumference

• The angle at the center is half the angle at the circumference

What is the new theorem introduced in the video?

• Angles in different segments

• Angles in the same segment

• Angles at the center

• Angles in a triangle

In the theorem of angles in the same segment, which points on the circle are crucial?

• Points on the circumference

• Points on the chord

• Points on the radius

• Points on the diameter

What is a chord in a circle?

• A line from the center to the circumference

• A line from one point on the circumference to another

• A line that divides the circle into two equal parts

• A line that is perpendicular to the radius

How many segments does a chord divide a circle into?

• One

• Four

• Three

• Two

What is the significance of the chord in the theorem of angles in the same segment?

• It divides the circle into equal parts

• It helps identify the segment

• It is perpendicular to the radius

• It is the longest line in the circle

When applying the theorem of angles in the same segment, what is not involved?

• The center of the circle

• The radius

• The circumference

• The chord

If two angles are in the same segment, what can be said about them?

• They are complementary

• They are supplementary

• They are equal

• They are different
