  • GEOMETRY - This is the branch of Mathematics that deals with the measurement, properties, and relationships of points, lines, angles, surfaces, and solids.
  • QUADRILATERAL - a closed plane figure consisting of four line segments or sides.
  • What is a Quadrilateral?
    Four-sided polygon
    Name using consecutive vertices.
    Have four angles
    The symbol square/cube (□) is used to denote a quadrilateral.
  • A quadrilateral has the following parts:
    4 sides
    4 angles
    4 vertices
    2 diagonals
  • Side - the segments that form the polygon.
  • Two sides with a common vertex are called consecutive sides.
  • Two sides of a quadrilateral are called opposite sides if they do not have a common endpoint.
  • Vertex - The common endpoint of two sides.
  • Angles - A pair of rays that have a common endpoint.
  • Diagonal - A line segment joining two nonconsecutive vertices of polygon.
  • PARALLELOGRAM - With two pairs of parallel sides.
  • RHOMBUS - With two pairs of congruent side
  • RECTANGLE - With four right angles.
  • SQUARE - Four congruent angles and four congruent sides.
  • TRAPEZOID - With exact one pair of parallel side.
  • KITE - With two pairs of consecutive sides that are congruent.
  • 1. A quadrilateral is a four-sided polygon.
    2. A quadrilateral has four angles.
    3. A quadrilateral is named using consecutive vertices.
    4. The symbol square is used to describe quadrilateral.
    5. Two pairs of parallel sides. (PARALLELOGRAM)
    6. Two pairs of congruent sides. (RHOMBUS)
    7. Four congruent ∠ four congruent sides. (SQUARE)
    8. Exact one pair of parallel sides. (TRAPEZOID)
    9. With four right angles. (RECTANGLE)
    10. With two pairs of consecutive sides that are congruent. (KITE)
  • There are two kinds of diagonal: convex and non-convex. CONVEX if the diagonals intersect
  • TRUE OR FALSE
    There are three ways to name an angle. You can name an angle by its vertex, by the three points of the angle (the middle point must be the vertex), or by a letter or number written within the opening of the angle.
    Answer: T
  • ALTITUDE - The height of a trapezoid
  • Base - The parallel sides of a trapezoid
  • LEGS - The non-parallel sides of a trapezoid
  • MEDIAN - It is the half the sum of the bases.
  • ASCALLENCE - trapezoid has no equal sides.
  • ARIGHT - trapezoid has a right angle.
  • ISOSCELES -trapezoid has congruent legs
