Project About Similarity and Congruence

What is the scale factor from ABCD to MNOP?

• 2/3

• 3/2

• 2

• 3

If the triangles are similar, find x

• 90

• 60

• 30

• 15

Given that the two triangles are similar,

find the value of X and Y.

• X=2.5 and Y=6.5

• X=6.5 and Y=2.5

• X=3 and Y=7

• X=2 and Y= 5

Complete the similarity statement.

• they are not similar

Complete the similarity statement.

What does congruent mean?

• Same shape, different size

• Not same shape, or size

• Same size, same shape

Which of the following is NOT true about similar figures?

• Similar figures always have the same shape.

• Similar figures always have the same size.

• Similar figures always have corresponding angles that are equal.

• Similar figures always have corresponding sides that are proportional.

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

• equal

• congruent

• proportional

• none of these

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

• reduction

• enlargement

• scale

• not proportional
