Module 2 Lesson 2 - Angle Relationships

What are vertical angles?

• Angles that are adjacent to each other when two lines intersect.

• Angles that are opposite each other when two lines intersect. They are always equal.

• Angles that are supplementary to each other when two lines intersect.

• Angles that are complementary to each other when two lines intersect.

If lines PR and QS are perpendicular, what can be said about the angles formed?

• The angles formed are acute angles, each measuring less than 90 degrees.

• The angles formed are obtuse angles, each measuring more than 90 degrees.

• The angles formed are right angles, each measuring 90 degrees.

• The angles formed are straight angles, each measuring 180 degrees.

What is the significance of angle relationships in geometry?

• Angle relationships are only important in trigonometry.

• Angle relationships help in solving problems related to shapes, sizes, and the properties of geometric figures.

• Angle relationships are irrelevant in modern geometry.

• Angle relationships are used solely for measuring angles.

Define supplementary angles.

• Two angles whose measures add up to 90 degrees.

• Two angles whose measures add up to 180 degrees.

• Two angles that are adjacent to each other.

• Two angles that are equal in measure.

How do you find the value of an unknown angle in a diagram with angle relationships?

• Use the properties of angle relationships (complementary, supplementary, etc.) to set up an equation and solve for the unknown angle.

• Measure the angle directly with a protractor.

• Estimate the angle based on the other angles in the diagram.

• Ignore the angle relationships and use trial and error.

• 60 degrees

• 70 degrees

• 80 degrees

• 90 degrees

What are angle relationships?

• Angle relationships refer to the ways in which angles interact with each other, including complementary, supplementary, vertical, and adjacent angles.

• Angle relationships are the measures of angles in degrees.

• Angle relationships are only about right angles and their properties.

• Angle relationships are irrelevant in geometry.

What is the measure of each angle formed by two intersecting lines?

• They are complementary angles and add up to 90 degrees.

• They are supplementary angles and add up to 180 degrees.

• The angles formed are vertical angles and are equal.

• The angles formed are adjacent angles and are unequal.
