Step-by-step explanation:
<u>Determining the length of BC</u>
From the diagram, it is clear that
- The point B is located at (-8, 10) and point C is located at (8, 10)
Since points A and C are located on a horizontal straight line. Thus, the length of BC can be determined by counting the x-axis units from reaching x = -8 to x = 8. i.e. 8-(-8) = 8+8 = 16
Thus, the length of BC = 16 units
<u>Determining the length of CD</u>
Given
- C (8, 10)
- D (2, -2)
The distance between C(8, 10) and D(2, -2)
Thus, the length of CD units
<u>Determining the length of ED</u>
Given
- E (-8, -4)
- D (2, -2)
The distance between E(-8, -4) and D(2, -2)
Thus, the length of ED units
<u>Determining the length of EB</u>
From the diagram, it is clear that
- The point E is located at (-8, -4) and the point B is located at (-8, 10)
Since points E and B are located on a vertical straight line. Thus, the length of EB can be determined by counting the y-axis units from reaching y = -4 to y = 10. i.e. 10-(-4) = 10+4 = 14
Thus, the length of EB = 14 units
Answer:
a) ΔF'G'H' is the image of ΔFGH
b)Center of dilation (7,-1)
c) Scale factor:
Step-by-step explanation:
Question a
Since the smaller triangle is named F'G'H', it means that, it is the image of triangle FGH.
Question B.
To find the center of dilation, draw straight lines through any two corresponding points.
The straight lines will meet at (7,-1).
This is called the center of dilation.
See graph in attachment.
Question c
The scale factor of the dilation is given by;
