Exploring Angle Types and Their Relationships

What does an angle measure in terms of two rays?

• The length of the vertex

• The space between them measured in degrees

• The curvature of the path connecting them

• The distance between their endpoints

What is an acute angle?

• An angle less than 90 degrees

• An angle greater than 90 degrees

• An angle exactly 90 degrees

• An angle greater than 180 degrees

What type of angle is exactly 90 degrees?

• Right angle

• Straight angle

• Acute angle

• Obtuse angle

What are vertical angles?

• Angles that add up to 90 degrees

• Angles that are adjacent to each other

• Angles directly opposite to each other when two lines cross

• Angles that add up to 180 degrees

What defines supplementary angles?

• Angles that are equal to each other

• Angles that add up to 90 degrees

• Angles that are opposite to each other

• Angles that are next to each other and add up to 180 degrees

Which angles are called complementary?

• Angles that add up to 90 degrees

• Angles that are opposite to each other

• Angles that add up to 180 degrees

• Angles that are equal to each other

What are parallel lines?

• Lines that intersect at a right angle

• Lines that never intersect

• Lines that intersect at an obtuse angle

• Lines that are perpendicular to each other

What theorem states that alternate interior angles are equal?

• The alternate interior angles theorem

• The corresponding angles theorem

• The supplementary angles theorem

• The vertical angles theorem

How do you solve for the value of 'X' in complementary angles set to 3X and X+10?

• 4X + 10 = 180

• 4X + 10 = 90

• 3X + X = 90

• X + 10 = 90

What is the minimum number of line segments required to form a shape?

• Four

• One

• Three

• Two
