## Power of a point (Internal P)

## Analysis 1

Change the position of points P, C or D and compare the results of the operations. Do they stay the same? Change the radius measurement. Do the operations results stay the same?

## Analysis 2

Write a property for what you saw. You can use the following terms: chords, segments, divide, result, etc

## Proof

## POWER of a point (EXTERNAL OR INTERNAL)

## Analysis 3

Change the position of points P, C or D and compare the results of the operations. Do they stay the same? Change the radius measurement. Do the operations' results stay the same?

## Analysis 4

Write a property for what you saw. You can use the following terms: chords, segments, divide, result, etc.

## Proof

## Power of a point with a tangent and a secant

## Reflexão 5

Write a property for what you saw. You can use the following terms: chords, segments, divide, result, etc.
