How do the angles of triangle ABC compare to
the measures of corresponding angles of triangle
ABC?

• A. Angle measures
• are 2.5 times
• larger

• B. Angles measures
• are the same

16
Are the triangles similar? Explain?

• B. The triangles are not
• similar because they do
• not have the same shape

• A. The triangles are
• similar just because
• they look the same.

• C. The triangles are
• are not similar,
• because the same
• thing is not
• happening to the
• x and y values.

• D. The triangles are
• similar because the
• angles are the same
• and their side lengths
• have increased by the
• same scale factor

17
The triangles are similar because the angles are
the same and their side lengths have increased by
the same scale factor.

20
How do the angles of the new triangle compare
to the angles of triangle ABC?

• A. Two of the angles are
• not the same. Only
• the right angle
• remained the same.

• B. All of the angles
• the same.

• C. All of the angles are
• different.

• D. None of the
• previous answers

21
Two of the angles are not the same. Only the
right angle remained the same.

22
Are the two triangles similar? Explain

• B. The triangles are similar,
• because they look
• the same and the same thing
• is happening to the x and y
• values.

• A. Answer not listed

• D. The triangles are not similar,
• because there is no scale
• factor that could be used to
• transform one triangle to
• another. All corresponding
• angles do not have the same
• measure.

• C. The triangles are not
• similar, because they do
• not look the same and
• none of the angles have
• the same measure.

23
The triangles are not similar, because
there is no scale factor that could
be used to transform one triangle
to another. All corresponding
angles do not have the same
measure.
