    • Geometry In The Real World Meredith Bach B.2
    • Point
      • A point is the exact location in space.
    • Line Segment
      • A line segment is a line between two different points.
    • Plane
      • A plane is a flat surface that extends forever.
    • Angle
      • An angle is two rays sharing a common endpoint, which is the vertex.
    • Perpendicular Lines
      • Perpendicular lines are lines that intersect forming a right angle.
    • Parallel Lines
      • Parallel lines are lines that are the same distance apart at any given point, and they never intersect.
    • Triangle
      • A triangle is a three-sided polygon.
    • Right Triangle
      • A right triangle is a triangle with a 90° angle.
    • Pentagon
      • A pentagon is a polygon with five sides.
    • Hexagon
      • A hexagon is a polygon with six sides.
    • Square
      • A square is a polygon with four equal sides.
    • Rectangle
      • A rectangle is a parallelogram with four right angles and two sets of parallel lines.
    • Trapezoid
      • A trapezoid is a four-sided figure with one pair of parallel lines.
    • Circle
      • A circle is a plane curve everywhere equidistant from a given fixed point.
    • Cylinder
      • A cylinder is a three- dimensional solid with two parallel circular ends.
    • Parallelogram
      • Quadrilateral with two pairs of parallel sides.
    • Sphere
      • A sphere is a perfectly round geometrical object in three-dimensional space.
    • Octagon
      • An octagon is an eight-sided polygon.
    • Acute Triangle
      • An acute triangle is a triangle with its angles less than 90°.
    • Obtuse Angle
      • An obtuse triangle is a triangle with an angle larger than 90°.
