These are correct statements:

<span>- Line segments AB and CD are parallel.

- </span>Since ∠1 and ∠3 are corresponding angles, they are congruent.

These are incorrect statements:

- <span>Since ∠3 and ∠4 are corresponding angles, they are congruent. **They are not corresponding angles, they are supplementary meaning they, together, equal 180.**

- </span><span>Since ∠1 and ∠2 are corresponding angles, they are congruent. **These are also not corresponding, they are supplementary.**

- </span><span>Line segments AB and CD are perpendicular. **They are not crossing over each other.**</span>** **

-** **<span>Since ∠1 and ∠4 are alternate interior angles, they are congruent. **They are not corresponding, they are supplementary. **</span><span>∠1 and </span><span>∠3 are corresponding just like </span>∠2 and <span>∠4. </span>

**Answer:**

**Step-by-step explanation:**

Males proportion who did not lose weight = 12/50 = 24%

Females proportion who did not lose weight = 15/100 = 15%

Thus we find this was effective for females compared to males.

he new weight-loss supplement was more effective on females in the study because only 15% of them failed to lose weight after two weeks, whereas 24% of the males failed to lose weight after two weeks.

So answer is Females, 15 and 24.
