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:
Step-by-step explanation:
two semicircles each of diameter 8 inches makes one circle with diameter=8 in.
radius r=8/2=4 in.
area of shaded region= πr^2=π×4²=16 π in²
≈16×3.14
≈50.24
≈50.2 in²

And add 8, 7 times
Answer:
CED or AEB
Step-by-step explanation:
adjacent angles share the same vertex and one side so it will be either CED or AEB
Answer:
a= 3
b=-4
c=-8
Step-by-step explanation:
3x²=4x+8
since the 4X is positive it will cross the equal sign and become negative and the same goes for 8,and this will leave nothing on the right of the equal sign therefore it will become 0
3x²-4x- 8= 0
the above equation is now in the form required
ax²+bx+c=0
so substitute the values according and u will see that a= 3
b=-4 and c=-8
hope this helps
