# Soccer 2v2 - Positioning, Angles, and Dilations

## Adding More Players

## 1. Predict

OffenseA has the ball, and needs to make a split-second decision. She is deciding between shooting or passing to her teammate, OffenseB. Which do you think is the better decision and why? Explain your reasoning in 2-3 sentences.

## 2. Investigate

## Soccer - 2v2 Example

## 2a - She takes the shot

Suppose OffenseA has the ball and **decides to shoot**.
**How much of the goal **is covered by the goalkeeper's dilation?
**Where** does the dilation of DefenderA end up if we use this point as the center of our dilation?

## 2b - She passes

**Change the checkboxes so that OffenseB has the ball now.**
How did this change the images on the dilation?
Are they in the same spot as in 2a?
**Describe** how the images are positioned compared to the center of dilation.

## 2c - Other Observations

What other geometric properties (**angles**, **area**, **midpoints**, **parallel lines**) did you find in the scenario?
Record your observations.

## 3. Revise

Now revisit your initial answer.
Would you change your advice from part 1, or make the same suggestion?
**Justify **your response with some of your observations from part 2.

## 4. Create

Design a different "Pass or shoot" scenario in the applet below. In the text box, explain who has the ball, which choice you'd recommend (pass or shoot), and why.
