Question

1. which statement is true about the quadrilateral shown? circle all that apply.

a. all angles are right angles
b. opposite sides are congruent
c. all sides are congruent
d. the figure has 3 pairs of perpendicular lines

1. which shape contains perpendicular lines?
2. which diagram correctly represents \\(\overrightarrow{pq}\\)?

Explanation:

For question 3: The quadrilateral has tick marks showing only opposite sides are congruent. It does not have right angle markers, so angles are not right angles; not all sides are congruent; and there are no perpendicular angle markers, so no 3 pairs of perpendicular lines.
For question 4: The second shape (a rectangle) has four right angles, meaning its adjacent sides are perpendicular (forming 4 pairs of perpendicular lines), while the first parallelogram does not have perpendicular sides.
For question 6: $\overleftrightarrow{PQ}$ is a line, which extends infinitely in both directions, matching option C.

Answer:

1. B. Opposite sides are congruent
2. The second (rectangular) shape
3. C. <Diagram with line PQ having arrows on both ends>
