Euclid’s Five Postulates
GEOMETRY
I.
Any two points can be joined by a
straight line segment.
II.
A straight line segment can be extended
infinitely in either direction.
III. A straight line segment of any length can
be used as a circle’s radius, with one
endpoint serving as the circle’s center.
IV. All right angles are congruent.
V.
If two lines intersect a third line in away
that their inner angles add up to less
than 180 degrees, those two lines will
intersect on that same side, forming a
triangle with the third line.
What did Archimedes shout when he
discovered the concept of
displacement?
Eureka!
What is the term that we use to describe the idea
that any solid object, when placed in water,
experiences an upward buoyant force
equal to the weight of the water it displaces?
The Archimedes’ Principle
The King of Syracuse asked
Archimedes to help him with a very
complex problem.
What was the King’s name?
King Hiero
What is the formula for
calculating the volume of a solid,
irregular object?
Final Volume – Starting Volume = Volume of Object
