As it relates to geometry, what does it mean for figures to be similar?

• corresponding sides are proportional and corresponding angles are congruent

• corresponding sides and angles are congruent

• angles are similar, and side lengths are the same, producing a figure that looks very close to another one.

• neither sides or angles are congruent

Given to the two figure to the left which of the following are true, select all that apply.

• The two figures are similar

• All the corresponding angles are congruent

• All the corresponding sides are proportional by a scale factor of 2:1

• The measure of MN= 2.5 cms

• Twice the measure of angle R is the value of angle N

If two figures are similar, their angles are (a)   ,

If two figures are similar, their sides are ​ (b)  

• congruent

• supplementary

• complementary

• Proportional

• vertical

• linear

• proof

• Two figures are similar if they have the same ​ (a)   but may have different ​ (b)   .

• shape

• sizes

• angles

If two figures are similar, they have the same ​ (a)   but are ​ (b)   in size. Their ​angles are ​ (c)   ​

• shape

• different

• congruent

• size

• the same

• proportional
