Understanding Adjacent and Consecutive Angles

The video explains adjacent and consecutive angles using quadrilaterals. Adjacent angles share a common line and vertex, while consecutive angles share a common line and are next to each other. Examples using a trapezoid illustrate these concepts, highlighting the differences between adjacent and consecutive angles.

What is the main topic introduced in the video?

• Circle theorems

• Triangles

• Adjacent and consecutive angles

• Parallel lines

Which of the following best describes adjacent angles?

• Angles that are equal in measure

• Angles that form a straight line

• Angles that share a common line and vertex

• Angles that are opposite each other

What do consecutive angles share?

• A common line and are next to each other

• The same measure

• A common vertex

• A perpendicular line

In a trapezoid, which pair of angles are considered consecutive?

• Angles that are opposite each other

• Angles that are next to each other and share a common line

• Angles that are equal

• Angles that form a right angle

Which of the following is true about angles A and B in a trapezoid?

• They are complementary angles

• They are supplementary angles

• They are consecutive angles

• They are adjacent angles

What is the key difference between adjacent and consecutive angles?

• Adjacent angles are always equal, while consecutive angles are not

• Adjacent angles share a common line and vertex, while consecutive angles are next to each other

• Adjacent angles form a straight line, while consecutive angles do not

• Adjacent angles are always right angles, while consecutive angles are not

In the example with diagonals, which angles are adjacent?

• Angles that are equal

• Angles that share a common line and vertex

• Angles that are opposite each other

• Angles that form a right angle

What is the common feature of adjacent angles?

• They are always equal

• They share a common line and vertex

• They form a straight line

• They are always right angles

Which angles in the example are described as having a common line and being next to each other?

• Adjacent angles

• Consecutive angles

• Vertical angles

• Supplementary angles
