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.
Answer: The mean is 6.
Step-by-step explanation: First you add all of the numbers together getting a total of 48. Next to find the mean you divide them by the total number of "dots". Lastly, you get the answer of 6 which is your mean.
<h2><u>
Answer:</u></h2>
7m^2 - 11m - 2
<h2><u>
Step-by-step explanation:</u></h2>
Distribute the negative.
4m^2 - m + 2 + 3m^2 - 10m - 4 = ?
Now, add the like terms.
4m^2 + 3m^2 = 7m^2
-m + (-10m) = -11m
2 + (-4) = -2
7m^2 - 11m - 2
3 was not multiplied by -4
It should be :
3(p - 4) = 3p - 12
