How do you determine if polygons are similar?
Vikentia [17]

Answer:

  a) corresponding angles of similar polygons are congruent

  b) corresponding sides of similar polygons are proportional

  c) a triangle is a polygon

Step-by-step explanation:

By <em>definition</em>, similar polygons have congruent corresponding angles and proportional corresponding sides.

A triangle is a polygon, so two triangles will be similar if they have congruent corresponding angles and proportional corresponding sides.

___

For an n-sided polygon, one only needs to show the conditions are met for n-1 angles and sides. Those will determine the measures of the final angle/side.

DaniilM [7]

Answer: The required exponential model is 1804(1.04)^t

Step-by-step explanation:

Since we have given that

Initial cases = 1804

Rate of growth = 4%

Since it is increasing exponentially,

So, it becomes,

A=ab^t

Here, a = 1804

b = 1+r=1+0.04=1.04

So, it becomes,

A=1804(1.04)^t

Hence, the required exponential model is 1804(1.04)^t
