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:
2x^4 + x^3 - 2x -1
Step-by-step explanation:
Do each one at a time and add them after you are done is necessary, first multiply 2x times x^3 this gives 2x^4. Then multiply 1 times x^3 to get x^3. Then multiply 2x times -1 to get -2x. Then multiply -1 and +1 to get -1. Then combine them together. None of the terms are like terms so you don't need to worry about combining them further but keep that in mind for other problems. The final answer becomes 2x^4 + X^3 - 2x -1 because none of the terms are the same power.
Answer:
-4
Step-by-step explanation:
Because if you look on a number line, -4 is more on the left, and because it is smaller.
