The scale factor of dilation from ABC to is 0.333.
Step-by-step explanation:
Step 1:
First, we plot the coordinates of both triangles.
The coordinates of the triangle are as follows;
= (2, 3),
= (2, 1), and
= (3, 1).
The coordinates of triangle ABC are;
A = (4, 9), B = (4, 3), and C = (7, 3).
Step 2;
Next, we need to find the distances between at least two coordinates for both triangles.
The distances between vertical lines are found by calculating the difference in y values while for horizontal lines, the distances are found by calculating the difference between the x values.
The distance of , the distance of
.
The distance of AB the distance of BC
Step 3;
To calculate the scale factor, we divide the measurement after scaling by the same measurement before scaling.
In this case, it is the length of the AB.
So The scale factor for AB =
The scale factor for BC =
Answer:
(-2, 3)
Step-by-step explanation:
A is translated from (5, 1) to A' at (6, -2).
That is, it moves <em>one unit to the right and three units down</em>.
B is also translated to B' one unit to the right and three units down to (-1, 0).
B must be <em>one unit to the left and three units above B'</em>.
Thus, the coordinates of B are (-2, 3).
The diagram below shows the translation of side AB of ∆ABC to its new location at A'B'.
