Question

1. is this a line of symmetry for this rectangle? why or why not? image of a red rectangle with its two diagonals drawn \bigcirc yes, because they go through the middle of the figure. \bigcirc no. when the rectangle is folded along these lines, the sides do not match up exactly. \bigcirc no, because they go through the middle of the figure. \bigcirc yes. when the rectangle is folded along these lines, the sides do not match up exactly.

Explanation:

A line of symmetry divides a shape into two mirror-image halves that match exactly when folded. The diagonals of a rectangle do not create matching halves when folded—one side would overlap a longer/shorter side instead of a congruent part.

Answer:

No. When the rectangle is folded along these lines, the sides do not match up exactly.
