If a series of rigid transformations maps ∠E onto ∠B where ∠E is congruent to ∠B, then which of the following statements is true
?
triangles ABC and FDE, in which angles A and D are right angles
ΔABC ~ ΔFDE because of the definition of similarity in terms of similarity transformations
segment DE ~ segment AB because corresponding parts of similar triangles are proportional
ΔABC ~ ΔFDE because of the AA similarity postulate
segment DE ~ segment AB because of the definition of similarity in terms of similarity transformations

Answer:
2, 4.5 and 8
Step-by-step explanation:
(1)
The mode is the number which occurs most often , then
mode = 2
(2)
The median is the middle value of the numbers arranged in ascending order. If there is no exact middle value then it is the average of the numbers either side of the middle.
1, 2, 2, 3, 4, 5, 6, 7, 8, 9
↑ middle
median = =
= 4.5
(3)
The range is the difference between the largest and smallest values
range = 9 - 1 = 8
