OBJECTIVE
  • By the end of the lesson, you will be able to
    identify and compare lines, line segments, rays,
    and angles.

3
GEOMETRIC FIGURES
  • LINE
  • A line is a straight path that goes on
  • without end in two directions.

The arrows show that the line does not end.
4
GEOMETRIC FIGURES
  • LINE SEGMENT
  • A line segment is a part of a line.
  • It has two end points.

5
GEOMETRIC FIGURES
  • RAY
  • A ray is part of a line.
  • It has one endpoint.
  • A ray goes on without end in one direction.

6
GEOMETRIC FIGURES
  • PARALLEL LINES
  • Parallel lines are the same distance
  • apart and never meet.

7
GEOMETRIC FIGURES
  • INTERSECTING LINES
  • Intersecting lines cross at a common
  • point.

8
GEOMETRIC FIGURES
  • PERPENDICULAR LINES
  • Perpendicular lines cross at right
  • angles.

9
GEOMETRIC FIGURES
  • ANGLE
  • An angle is formed by two rays with the
  • same endpoint.

10
GEOMETRIC FIGURES
  • RIGHT ANGLE
  • A right angle has a square corner.
  • It measures 90 º.

11
GEOMETRIC FIGURES
  • ACUTE ANGLE
  • Some angles are less than a right
  • angle.
  • They are acute angles.

12
GEOMETRIC FIGURES
  • OBTUSE ANGLE
  • Some angles are greater than a right
  • angle.
  • They are obtuse angles.
