Geometry Vocab: Topics 1 & 2

What is a point?

• A location with size

• A location with no size

• A plane with no end

• A line with no thickness

How is a line named?

• All of the above

• With a lowercase letter

• With a capital letter

• With 2 points on the line

What is a plane?

• A flat surface with no end

• A location with no size

• A line with no thickness

• A straight path with no thickness

What are collinear points?

• Points with infinite thickness

• Points with no size

• Points on the same plane

• Points on the same line

What is a line segment?

• A part of a plane with 2 endpoints

• A part of a plane with 1 endpoint

• A part of a line with 3 points

• A part of a line with 1 endpoint

What is a ray?

• A part of a line with 2 endpoints

• A part of a plane with 1 endpoint

• A part of a line with 1 endpoint

• A part of a plane with 2 endpoints

What are opposite rays?

• Rays with different endpoints

• Rays with the same endpoint

• Rays on different planes

• Rays on different lines

What is the midpoint of a line segment?

• The point that divides the segment into 2 perpendicular line segments

• The point that divides the segment into 2 equal line segments

• The point that divides the segment into 2 congruent line segments

• The point that divides the segment into 2 parallel line segments

What is the distance formula?

• d = √[( x₂ + x₁)² + (y₂ + y₁)²]

• d = ( x₂ + x₁)² + (y₂ + y₁)²

• d = √[( x₂ - x₁)² + (y₂ - y₁)²]

• d = ( x₂ - x₁)² + (y₂ - y₁)²
