How will I know when I am ready for the retake?

  • I know how to tell if two figures are similar.

  • I can write and solve a proportion to find missing sides of similar figures.

  • I know how to write a similarity statement.

  • I can use similarity postulates to determine if two triangles are similar.

What makes two figures similar?

  • Corresponding angles are congruent making them the same shape.

  • Corresponding sides are in proportion which makes them different sizes.

20

Multiple Choice

Question image

State if the pair triangles are similar. If they are similar, state how you know the triangles are similar.

1

Similar by SAS

2

Not Similar

3

Similar by SSS

4

Similar by SAS

21

Multiple Choice

Question image

Are these triangles similar? If so, what postulate is used?

1

Yes, ASA

2

Yes, AA

3

Yes SAS

4

No, the triangles are not similar.

22

What is a similarity transformation?

similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure. In other words, two figures are similar if a similarity transformation will carry the first figure to the second figure.

23

Multiple Choice

Question image

Are the two triangles similar? Explain.

1

Yes. Rotate ΔABC 90 degrees about point P. Then, dilate about point F with a scale factor of 0.5 to create ΔDEF..

2

Yes. reflect ΔABC across the x axis. Then, dilate about point F with a scale factor of 1.5 to create ΔDEF..

3

Yes. Rotate ΔABC 180 degrees about point P. Then, dilate about point F with a scale factor of 1.5 to create ΔDEF..

4

No the triangles are not similar because there is not a similarity transformation that maps one to the other.

24

Multiple Choice

Question image

Which series of transformations were performed in the figure?

1

Translation 5 units down, reflection over the y-axis

2

Reflection over the x-axis, translation 6 units right

3

Rotation 90o clockwise, reflection over the x-axis

4

Rotation 180o clockwise, reflection over the y-axis

25

Multiple Choice

Question image

Quad OBCD is similar to Quad OHTE because:

1

Quad OBCD can be reflected over the x axis and then rotated 90 degrees

2

Quad OBCD can be reflected over the x-axis and then dilated about point O by a scale factor of 2.

3

Quad OBCD can be reflected over the y-axis and then dilated about the origin by a scale factor of 2.

4

Quad OBCD can be reflected over the y-axis and then dilated about the origin by a scale factor of 1/2.

26

Multiple Choice

Question image
