If two figures are similar, the corresponding sides are ______________.

• equal
• congruent
• proportional
• none of these

If two figures are similar their angles are______.

• proportional
• congruent
• supplementary
• complementary

Calculate the value of the scale factor between the 2 triangles

• 2.5

• 3

• 3.5

• 4

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

• x = 12
• x = 3
• x = 40
• x = 4

What is the value of X?

• X=4
• X=6
• X=3
• X=2

Tell whether the two figures are congruent.

• Yes, same size and same shape
• No, same shape but different sizes
• No, different size and different shapes

If the scale factor is less than one, the new figure will be

• an enlargement
• a reduction
• a scale factor

If the scale factor is greater than one, the new figure will be

• a reduction
• an enlargement
• a scale
• not proportional

What is the scale factor?

• 1/2
• 7/3
• 2
• 10/3

Are the following similar? Why or why not?

• Yes, because the corresponding angles are congruent.
• No, the numbers are even
• No, the sides are 2 times larger, but the width is the same.
