Segment Addition Postulate Practice

Click and hold on point C. Move the point to the right until the measure of AC = 9. What is the measure of segment BC when segment AB = 4? (It's not enough to get the right answer, show your work).

Without changing the measure of AC, click and hold point B and move it to the right until AB = 7. What is the length of BC when AB = 7? (It's not enough to get the right answer, show your work)

Without changing the measure of AC, click and hold point B and move it until AB = 4.5. What is the length of BC when AB =4.5? (It's not enough to get the right answer, show your work) (You may need to use your calculator when adding and subtracting decimals.

When AB = 4.5, and AC = 9, what is true about the length of AB and BC?

Move point C until AC = 8.3. Slide point B until AB = 3.3. What is the length of BC? (It's not enough to get the right answer, show your work).

Without changing AC = 8.3, slide point B until BC = 3.3. What is the length of AB? (It's not enough to get the right answer, show and check your work).

Move point C until the length of AC = 11.7. Set point B so that BC = 6. What is the length of AB? (It's not enough to get the right answer, show your work).

Move CC until the length of AC = 11. What will happen to the measure of AB and BC when you place point B on the midpoint of the segment? What is the length of both segments at the midpoint?
