a.
To find:If two triangles are similar, determine what two transformations map
a.
Answer to Problem 18HP
First
And the dilated with a scale factor of
Explanation of Solution
Given information:
Two triangles
Coordinates of
Graph of Both triangles are
From graph
We can say that
First
And the dilated with a scale factor
As given both triangles are similar
Scale factor will ratio of any side of Image divided by corresponding side of Original triangle.
From graph we can say that
Therefore,
Scale factor
Therefore,
First
And the dilated with a scale factor of
b.
To find: The Coordinates of the vertices of the image.
b.
Answer to Problem 18HP
Vertices of the image are
Explanation of Solution
Given information:
Coordinates of
Given
Coordinates of
Translated Up ten units means y-coordinate of each vertex should be added with
Therefore,
New vertices are
Therefore,
Vertices of the image are
