Which polygons are similar? 1,2,3,4

1 and 4

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

The corresponding angles of Triangle 1 and Triangle 4 are congruent

therefore

Both triangles are similar

similar polygons are 1 and 4

Step-by-step explanation:

From the figure we can see some triangles and angles are given

Similar triangles means that the angles are same and their corresponding  sides are in proportion.

To find the correct answer

From the figure we get 1 and 2 are similar triangle, because angles of triangle 1 are 10°, 60° and 110°,

and angles of triangle 4 are 10°, 60° and 110°,

Therefore the correct answer is 1 and 4

if x = 1, then the answer is 3.5
