Lesson 5Problem 1Quadrilateral ABCD is dilated with center (0,0), taking B to B′. Draw A′B′C′D′.
Solution
Problem 2Triangles B and C have been built by dilating Triangle A.
Solution
SolutionProblem 2Triangles B and C have been built by dilating Triangle A.- Find the center of dilation.
- Triangle B is a dilation of A with approximately what scale factor?
- Triangle A is a dilation of B with approximately what scale factor?
- Triangle B is a dilation of C with approximately what scale factor?
- The center of dilation is here:
- 3
- 13
- 23
- Draw the dilation of triangle ABC, with center (0,0), and scale factor 2. Label this triangle A′B′C′.
- Draw the dilation of triangle ABC, with center (0,0), and scale factor 12. Label this triangle A″B″C″.
- Is A″B″C″ a dilation of triangle A′B′C′? If yes, what are the center of dilation and the scale factor?
Solution-
-
- Yes, A″B″C″ is a dilation of A′B′C′ with center (0,0) and scale factor 14.
