I will send you a geogebra file through airdrop. Once you get it you will see a triangle. All the angles of the triangle are named with a Greek letter and have a color don’t click on any of the boxes yet.
Part 1
Record the values of each interior angle of the triangle below.
(green)=________, (red) = _______________, (blue) = ________________.
Can you come up with a conjecture? If so what is it?
Now move the points A, B and C. Change the shape of the triangle and record the vales of the angles.
(green)=________, (red) = _______________, (blue) = ________________.
Is your conjecture still true after the second reading?__________.
Hint: add the angles.
Move the three points again.
(green)=________, (red) = _______________, (blue) = ________________.
Is your conjecture still true after the third reading? _____________
Hint add all the angles together for each reading what do they equal each time?
Reading one
______________
Reading two
______________
Reading three
______________
What is your final conjecture?
Part 2
Click on the show exterior angle rays, and click on the show exterior angle values. Three new exterior angles will show up.
Record the values of each interior and exterior angle below.
(green)=________, (red) = _______________, (blue) = ________________.
(brown)=________, )gray=________________, (orange) _______________.
Can you come up with a conjecture about a relationship with the interior and exterior angles.
Move the three point and record the values of the angles.
(green)=________, (red) = _______________, (blue) = ________________.
(brown)=________, (gray)=________________, (orange) _______________.
Does your previous conjecture true after the second reading?______________.
Hint: add to interior angles together and compare the sum to an exterior angle.
Move the points and take a third reading.
(green)=________, (red) = _______________, (blue) = ________________.
(brown)=________, )gray=________________, (orange) _______________.
Does your previous conjecture still true? _________________.
Hint: add the two interior angles together then compare their value with the exterior opposite angle to them.
Example add (green) + (red) ______________ compare the sum to (brown),
(green) + (blue)_______________ compare the sum to (orange)
(red)+(blue) _____________compare the sum to (grey).
In part one what is your final conjecture?
In pare two what is your final conjecture?
