Triangle \(DEF\) is a dilation of triangle \(ABC\) with scale factor 2. In triangle \(ABC\), the largest angle measures \(82^\circ\). What does the largest angle measure in triangle \(DEF\)?

Draw 2 polygons that are similar but could be mistaken for not being similar. Explain why they are similar.

These 2 triangles are similar. Find side lengths \(a\) and \(b\). Note: the 2 figures are not drawn to scale.

Jada claims that \(B’C’D’\) is a dilation of \(BCD\) using \(A\) as the center of dilation.

What are some ways you can convince Jada that her claim is not true?

<p>Point A, angle B C D and angle image B prime, C prime, D prime. Point A is above, then B C D and under all is B prime C prime D prime. B C D is smaller and appears to be obtuse. B prime C prime D prime is three times larger and appears to be right. </p>

1. Draw a horizontal line segment \(AB\).

2. Rotate segment \(AB\) \(90^\circ\) counterclockwise around point \(A\). Label any new points.
3. Rotate segment \(AB\) \(90^\circ\) clockwise around point \(B\). Label any new points.
4. Describe a transformation on segment \(AB\) you could use to finish building a square.
