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:
a) Triangle.
b) Triangle.
c) The area is 110 cm.
Step-by-step explanation:
The shape is given because it is a cross section of a Pyramid which we can see shaded in grey.
The area is given by the base times hight devided by 2. So 10cm * 22cm/2= 110cm.
Hope this helped ;)
I would say it’s c.
D is wrong cause definitions are proven right all the time.
B is wrong because a definition is not an arrangement of deductions
A is wrong because it says that the statement is not defined when it is.
You didn't attach anything, but this is how you should solve this equation: given an equation
the solutions are

In your case, the values are
. If you plug these values inside the solving formula, you have

So, the two solutions are 1 and 7
