Directions: Identify each set of lines as parallel, perpendicular, or neither.
1 answer:
3 ans: Perpendicular
Explanation:
Since, we can see that two line intersect each other at the angle of 90°. Thus it's perpendicular.
4 ans: Neither
Explanation:
We, can observe that the two lines aren't intersecting or equal to each other. These lines might meet a point. Therefore, these lines are neither.
5 ans: Parallel
Explanation:
6 ans: Perpendicular
Explanation:
Since, these lines are at equal distance from each other. These lines won't meet at any point. Thus, these are parallel lines.
7 ans: Parallel
Explanation:
Since, these lines are at equal distance from each other. These lines won't meet at any point. Thus, these are parallel lines.
8 ans: Perpendicular
Explanation:
Since, we can see that two line intersect each other at the angle of 90°. Thus it's perpendicular.

If the shape on the red image is scaled to the shape on the blue image, the scale factor is 0.2777.
Explanation:
- The original shape's base in the red image is measured. The base of the red image is measured to be 9 units. Now we measure the same side of the blue image. The base of the blue image is measured to be 2.5 units. So after scaling, the length of the painting will be 2.5 units.
- To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling. In this case, it is the base of both images. So The scale factor =
=
= 0.2777.
- So the red image is dilated by a scale factor of 0.2777 to produce the blue image.
