Exploring Angle Relationships in Geometry

What defines adjacent angles?

• Angles that share a common vertex and side but have no common interior points.

• Angles that form a straight line when added together.

• Angles that are opposite to each other when lines intersect.

• Angles that sum up to 90 degrees.

How can you identify adjacent angles in a diagram?

• By finding angles that are opposite to each other.

• By locating angles that share a common vertex and side.

• By looking for angles that sum up to 180 degrees.

• By identifying angles that are both right angles.

What is true about vertical angles?

• They are always supplementary.

• They share a common side.

• They are congruent to each other.

• They sum up to 90 degrees.

What is a unique property of vertical angles?

• They share a common side.

• They are formed by two intersecting lines and are congruent.

• They sum up to 180 degrees.

• They are always right angles.

What do perpendicular lines create?

• Four congruent adjacent right angles.

• A pair of complementary angles.

• Two supplementary angles.

• Two acute angles.

What is the sum of complementary angles?

• 180 degrees

• 90 degrees

• 45 degrees

• 360 degrees

What is the sum of supplementary angles?

• 90 degrees

• 180 degrees

• 360 degrees

What characterizes a linear pair of angles?

• They are both acute angles.

• They form a straight line and sum up to 180 degrees.

• They sum up to 90 degrees.

• They are congruent.

What defines complementary angles?

• Angles that are adjacent to each other.

• Angles that sum up to 180 degrees.

• Angles whose measures add up to 90 degrees.

• Angles that form a linear pair.

What is the relationship between the angles in a linear pair?

• They are vertical angles.

• They are congruent.

• They are complementary.
