Similar Figures

Question 1

What is Similarity?

Answer 1

Similiar Figures are

Identical in Shape

BUT

not identical is size

Question 2

How do we identify if figures are similar?

Answer 2

All corresponding angles are equal

The ratios of corresponding sides are equal

Question 3

If ABCD is similar to PQRS

can we rewrite it as

ABCD is similar to SRQP

Answer 3

No, as the order of the sides must correspond

Question 4

If ABC is similar to DEF

AB : DE = ? : ?

BC : EF = ? : ?

CA : FD = ? : ?

Answer 4

AB : DE = 4 : 8

BC : EF = 3 : 6

CA : FD = 5 : 10

Question 5

Triangle ABC is similar to Triangle PQR

List out the corresponding angles

Answer 5

Triangle ABC is similar to Triangle PQR

Angle A = Angle P

Angle B = Angle Q

Angle C = Angle R

Question 6

Given the ratio of the corresponding sides

4 : 8

3 : 6

5 : 10

The ratios can be simplified to

Answer 6

1 : 2
