Chapter 5 Math Vocabulary

Key Definitions and Concepts

  • Perpendicular Lines

        Definition: Two lines that intersect to form right angles (90 degrees)..

  • Parallel Lines

    • Definition: Lines in the same plane that never intersect or cross.

  • Transversal

    • Definition: A line that intersects two or more other lines.

  • Alternate Interior Angles

    • Definition: Interior angles that lie on opposite sides of the transversal.

  • Alternate Exterior Angles

    • Definition: Exterior angles that lie on opposite sides of the transversal.

  • Corresponding Angles

    • Definition: Angles that are in the same position on two parallel lines in relation to a transversal.

  • Regular Polygon

    • Definition: A polygon that is both equilateral (all sides are equal) and equiangular (all angles are equal).

  • Legs

    • Definition: The two sides of a right triangle that form the right angle.

  • Hypotenuse

    • Definition: The side opposite the right angle in a right triangle.

  • Distance Formula


  • Pythagorean Theorem

    • Formula:
      a2+b2=c2a^2+b^2=c^2

  • Sum of the Measures of the Interior Angles of a Polygon

    • Formula: The sum can be calculated using the formula:
      (n−2)180(n-2)180
