1. Name the angle in the scaled copy that corresponds to angle
ABC.
2. Name the segment in the scaled copy that corresponds to
segment AD.
3. What is the scale factor from polygon ABCD to polygon
PORS?

1. Angle PQR

2. Segment PS

3. 3/2 = 1.5

Step-by-step explanation:

1. Angle PQR in the scaled copy is the angle in polygon PQRS that corresponds to angle ABC in polygon ABCD. They are both at the same position in the two different figures. They match each other.

2. Segment PS in the scaled copy is the segment in polygon PQRS that corresponds to segment AD in polygon ABCD. They match each other as they appear in similar spot.

3. The scale factor = the ratio of any of the corresponding segment length.

Let's consider segments lengths of AD in ABCD, which corresponds to segment PS in PQRS.

AD = 2 units

PQ = 3 units

Scale factor from ABCD to PQRS = PQ/AD = 3/2 = 1.5

The whole number tells us that ABCD is scaled up or enlarged to given a bigger polygon, PQRS.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
