Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

Geometry Conjectures

front 1

C-14 Median Concurrency

back 1

The three medians of a triangle are concurrent.

The point of Concurrency is called the centroid.

front 2

C-11 Altitude Concurrency

back 2

The three altitudes of a triangle are concurrent.

The point of concurrency is called the Orthocenter

front 3

C-10 Perpendicular Bisector Concurrent

back 3

The three Perpendicular Bisectors are concurrent.

The point of concurrency is called the circumcenter.

front 4

C-9: Angle Bisector Concurrency

back 4

The three angle bisectors of a
triangle meet at a point.
-or-
The three angle bisectors of a
triangle are concurrent.
C-9: Angle Bisector Concurrency
The point of concurrency is called the incenter

front 5

C-16: Center of Gravity

back 5

The centroid of a triangle is the
center of gravity of the triangular
region.

front 6

C-15: Centroid Conjecture

back 6

The centroid divides the median into
2 segments so that the distance
from the vertex to the centroid is
twice the distance from the centroid to the midpoint.

front 7

Orthocenter Conjectures

back 7

The orthocenter of a right triangle is
on the vertex of the right angle.

Altitudes
The orthocenter of an obtuse
triangle is outside of the triangle
Orthocenter Conjectures

front 8

C-12: Circumcenter Conjecture

back 8

The circumcenter is equidistant from
the vertices of a triangle.

Perpendicular Bisector
Other info:
a. The circumcenter is outside of an obtuse
triangle
b. The circumcenter is on the midpoint of the
hypotenuse of a right triangle
c. The circumcenter is the center of the circle that
circumscribes the triangle

front 9

C-13: Incenter Conjecture

back 9

The incenter is equidistant from the sides of a triangle.

Angle Bisector

Other info:
a. The incenter is the center of the circle that is
inscribed inside the triangle
b. Don’t forget that the distance in question is the
shortest distance, perpendicular from the
incenter to the side of the triangle

front 10

Euler Line Conjecture

back 10

The circumcenter, centroid and
orthocenter are collinear.
For an isosceles triangle, the points
of concurrency all lie on the angle
bisector of the vertex angle.
For an equilateral triangle, all 4
points of concurrency are the same

front 11

Euler Segment Conjecture

back 11

The centroid divides the Euler
Segment into 2 parts so that the
smaller part is half of the larger part.
