Study Notes

Geometry Assignment: Midpoint and Length

  • Midpoint of a Line Segment: The midpoint of a line segment is the point exactly halfway between the endpoints. To find the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂), use the midpoint formula: ((x₁ + x₂)/2, (y₁ + y₂)/2).

  • Examples:

    • For endpoints (8, 1) and (-8, 0): Midpoint is ((8 + (-8))/2, (1 + 0)/2) = (0, 0.5)
    • For endpoints (1, 6) and (2, -5): Midpoint is ((1 + 2)/2, (6 + (-5))/2) = (1.5, 0.5)
    • For endpoints (9, 10) and (1, -5): Midpoint is ((9 + 1)/2, (10 + (-5))/2) = (5, 2.5)

Finding the Length of a Line Segment

  • Use the distance formula: The distance between two points (x₁, y₁) and (x₂, y₂) is √((x₂ - x₁)² + (y₂ - y₁)²).

  • Example: For endpoints (0.5, 4.4) and (-2.3, 0.9) the distance is √((-2.3 - 0.5)² + (0.9 - 4.4)²) ≈ 4.5

Segment Addition Postulate

  • If B is between A and C, then AB + BC = AC. This shows how segments add up.

  • Example: If AC = 15 and AB = 10, then BC = 5.

Angle Addition Postulate

  • If point B lies in the interior of ∠AOC, then ∠AOB + ∠BOC = ∠AOC.

Coordinate Plane Distance

  • To find the distance between two points, use the distance formula: √((x₂ - x₁)² + (y₂ - y₁)²).

  • Example: The distance between (-4, 1) and (2, -5) is √((2 - (-4))² + (-5 - 1)²) = √(6² + (-6)²) = √72 = 6√2

Solving for Variables in Geometry Problems

  • Geometry problems often involve algebraic equations; use your knowledge of geometric principles and formulas to set up and solve these equations to find unknown values like x.
