Real World Examples
Jonathan McAuley
Point
Definition - A point is one place that shows a specific “point”
Real World Example - A pencil Point would be one. The tip of the
pencil represents one point and you could touch it on a piece of
paper and make a point or 2 to form a line.
Postulates, Theorems, and Corollaries - If 2 lines intersect, they
intersect exactly one point.
Line
Definition - A line goes on infinitely in both directions and expands
pass 2 points.
Real World Example - A real world example would be a
railroad bc it goes on in each direction.
Postulates, Theorems, and Corollaries - If a line goes through
2 points and goes on forever through 2 points it is a line.
Plane
Plane - A plane is 3 points that lie in the same place and expands infinitely
in all directions.
Real World Example - The Earth would be an example of a plane because
it expands in each direction.
Postulates, Theorems, and Corollaries - If two points lie in a plane, then the line containing those
points lies in the plane.
Segment
Definition - A segment is straight and finite.
Real World Example - A real world example would be poptart.
The edge of the poptart is straight and doesn’t go on forever in
either direction.
Postulates, Theorems, and Corollaries - “Segment Addition.”
If B is between A and C, then B + BC = AC
Ray
Definition - A ray goes infinitely in only one direction.
Real World Example - A tennis player serving a tennis ball could
be an example of a ray bc it goes in 1 direction.
Postulates, Theorems, and Corollaries -
Collinear Points
Definition - It is 3 points that are all on the same line.
Real World Example - These 3 people sitting next to each other is an
example of this.
Postulates, Theorems, and Corollaries -
Acute Angle
Definition - It’s an angle less than 90 degrees.
Real World Example - A real world example would be a single slice
of Pizza. This picture especially shows bc it shows the pizza and the
position it came from because it is also an acute angle.
Postulates, Theorems, and Corollaries -
Obtuse Angle
Definition - It’s an angle greater than 90 degrees.
Real World Example - A boomerang would be a real world example because
the inside and shape of it is more than 90 degrees.
Postulates, Theorems, and Corollaires -
Right Angle
Definition - Its an angle that is equal to 90 degrees.
Real World Example - The bottom of the chair with the chair legs are an example.
Postulates, Theorems, and Corollaries -
Perpendicular Lines
Definition - 2 Lines intersect to form a 90 degrees angles.
Real World Example - A cross has 4 90 degree angles and definitely represents this.
Postulates, Theorems, and Corollaries -
Complementary Angles
Definition - 2 Angles to form 90 degrees.
Real World Example - I have 2 real world examples. One is an
cross roads which forms a 90 degrees angle and the other is a
corner of a cross that also forms a 90 degree angle.
Postulates, Theorems, and Corollaries -
Supplementary Angles
Definition - 2 angles to make 180 degrees angle.
Real World Example - This road shows a 180 degree angle.
Right Triangles
Definition - A triangle that has a 90 degrees angle (Right angle) The side is
also 90 so the other 2 are 45.
Real World Example - Half a sandwich would be an example because you
can see it has a right angle.
Vertical Angles
Definition - They’re are the angles opposite of eachother when
lines cross and they are always equal.
Real World Example - A railroad cross sign is an example
because they cross to form angles across from each other that
are equal.
Equilateral Triangles
Definition - All sides of a triangle are the same.
Real World Example - A pool triangle could be an example because all
3 sides are equal in distance.
Acute Triangle
Definition - A triangle that has an angle less than 90 degrees.
Real World Example - A runner running down a slope is one because it is
going down because of the angle being smaller and less than 90.
Isosceles Triangle
Definition - It’s a triangle that has 2 equal sides and 2 equal angles.
Real World Example - A clothes hanger is an example because it forms down
and 2 of the sides are equal and the other is longer.
Obtuse Triangle
Definition - It’s a triangle that has an angle greater than 90 degrees.
Real World Example - A fanner be an example because it expands out
a little further and forms an obtuse angle.
Scalene Triangle
Definition - It’s a triangle with no equal sides.
Real World Example - The shaping of this bicycle is one
because the triangle in it has 3 unequal sides in measure.
