    Study Notes

    Geometry Study Notes

    • Geometry covers shapes, lines, and angles
    • Points, lines, and planes are undefined terms
    • Segments, lines, and rays are defined terms
    • Congruent segments are segments of equal length
    • Collinear points are points that lie on the same line
    • Coplanar points are points that lie in the same plane
    • A segment bisector is a point, ray, line, line segment, or plane that intersects the segment at its midpoint
    • The midpoint of a segment divides it into two congruent segments
    • The Ruler Postulate states that the points on a line can be matched one-to-one with the real numbers; The coordinate of a point is the real number that corresponds to it
    • The distance between two points A and B, written as AB, is the absolute value of the difference of the coordinates of A and B.
    • The Segment Addition Postulate states that if B is between A and C, then AB + BC = AC. If AB + BC = AC, then B is between A and C.
    • The Distance Formula is: AB = √(x2 - x₁)2 + (y2 - y1)2
    • The Midpoint Formula is: M(x1+x2 / 2, y1+y2 /2)
    • Understanding angle pair relationships, such as complementary, supplementary, adjacent, and vertical angles, is key to solving problems involving angles
    • Complementary angles are two angles whose measures have a sum of 90 degrees
    • Supplementary angles are two angles whose measures have a sum of 180 degrees
    • Adjacent angles have a common vertex and a common side but do not overlap.
    • Vertical angles are a pair of opposite congruent angles formed by intersecting lines
    • Linear pairs are adjacent angles that form a straight line
