Answer 1

Circle Conjectures Project


You have been hired to work for the great Euclid, Father of Geometry. While working
for him, you will be asked to explore different principles related to circles. He is depending
on you to determine some “truths” regarding line segments and circles so that he can teach
others. Your job is to experiment with different types of circles and lines by following sets
instructions, and then write the truths, or conjectures, that go with your experiment. You
must use the correct vocabulary, be patient and cautious in your work, keep labels and measurements accurate, and show all of your work…after all, Euclid’s reputation is at stake!

TASK: Relationship of a tangent line and the radius drawn to a point of tangency.

Experiment Procedure:
 Construct a circle with a set radius length, record in cm. Label the center O.
 Using a straightedge, draw a line segment SR that appears to touch the circle at only ONE point. Label the point of tangency T.
 Construct OT. Measure and record length.
 Use your protractor to measure the angles at T. Record your measurements in the table below.
 Repeat with FOUR different sized circles.

Answer 3

what are you unclear on?

Answer 4

Im having trouble with all of it.

Answer 5

just start by drawing a circle using a compass or protractor

Answer 6

Like that?

Answer 7

yeah, but if you're using paper, make sure to use the right tools

Answer 8

(like, don't just estimate, use a compass)

Answer 9

if you don't have one, just grab something with a round base

Answer 10

I half to do it online. Im homeschooled.

Answer 11

oh ok, then you're good

Answer 12

now label the center "O"

Answer 13

make sure to draw the actual point like this

Answer 14

oh ok i got ya.

Answer 15

now, draw a line SR that touches the circle on the edge

Answer 16

no, it needs to touch the circle

Answer 17

oh ok hold on
