HW #4

Are these triangles similar?

• Yes
• No

The pair of figures is similar. Find the missing side.

• x = 12
• x = 3
• x = 40
• x = 4

What does congruent mean?

• corresponding sides and angles are congruent

• corresponding sides are proportional and corresponding angles are congruent

• sames shape

• neither sides or angles are congruent

Name the transformation.

• Translation
• Reflection
• Rotation

The image shows what type of transformation

• Rotation
• Translation
• Reflection

What transformation is happening to the red triangle to get to the blue triangle?

• Translation
• Rotation
• Reflection

Which series of transformations were performed in the figure?

• Translation 5 units down, reflection over the y-axis

• Reflection over the x-axis, translation 6 units right

• Rotation 90^o clockwise, reflection over the x-axis

• Rotation 180^o clockwise, reflection over the y-axis

When two shapes have different sizes and angles, they are...

• congruent
• similar
• neither congruent or similar

Determine if the two figures are similar by using transformations.

• similar; a reflection and a dilation map one figure onto the other.

• similar; a rotation and a dilation map one figure onto the other.

• similar; a translation and a dilation map one figure onto the other.

• The figures are not similar.

The smaller triangle is transformed to create the larger triangle. Which of these is the scale factor of the dilation center at the origin?

• 4

• 2

• 1

• 1/2
