1. Probability
-the measure of how likely an event is to
happen.
Experiment
-an activity with observable results.
Outcomes
- the result of an experiment
Sample space
- the result of all possible outcomes of the
experiment.
Event
- the subset of the sample space

2. Coin

8. Geometry
- the branch of
mathematics concerned
with the properties and
relations of points, lines,
surfaces, solids, and
higher dimensional

10. LINE - is straight (no
curves),has no thickness, and
extends in both directions
without end.
LINE SEGMENT - is a
straight line which joins two
points but does not extend
beyond them.
RAY - is a line that has one end

11. AB

19. KINDS OF ANGLE
1.ACUTE ANGLE – An angle that
measures more than 0° and
less than 90°.
2.OBTUSE ANGLE – Any angle
greater than 90° and smaller
than 180°.
3.RIGHT ANGLE – is an angle
that has a measure exactly
90°.

27. Naming Angles
Example:
Names:
<WET
<1
<TEW

28. Parallel Lines stay the
same distance apart and
never touch.
Perpendicular Lines are
lines that meet or cross and
form right angles.
Intersecting Lines meet or
cross each other.

30. NAMES and SYMBOLS
