6.2 -Similar Figures review

What are the two rules that need to be proven before we call two shapes similar?

• Side lengths have to be the same size

• Angles have to be the same size

• Side length ratios have to be the same

• Angle size ratios have to be the same

Using the image match the following Angles.

• C

• A

• T

• E

• R

• C

These two shapes are​ (a)   because ​ (b)  

• not similar
• similar
• not all the angles match
• all the angles match

Are these shapes similar?

• Yes

• No

These shapes are similar because​ (a)   you can find it because all they should add up to ​ (b)  

• all the angles match
• side length ratios are the same.
• 360
• 180

For parallelograms to be similar the side have to have the same (a)   .

Are these two shapes similar

• Yes

• No

If you were to prove these two shapes are similar what is their ratio? Remember to place it in a fraction (smaller/larger)
