State if the triangles in each pair are similar. If so, state how you know they are similar and complete the similarity statement.

1) They are similar because they both have a same degree angle and are vertical/mirror triangles

2)They are not similar because the bottom one is 90 and 73 and the top one is 20 and 15 which means they top is smaller than the bottom.

I hope this helps!

worked it out i believe

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
