Which is a property of polygons?

Mathematics

snow_lady [41]2 years ago
3 0

Answer:

A polygon is a plane figure.

Step-by-step explanation:

This means it is a 2 dimensional shape that lies flat, it has length and width, it has area but no thickness.

There is no max number of sides, so the first answer is not right.

In math, saying it is solid means its 3-d, so that is not right (it's only 2-d)

Saying its open, means that somewhere on the shape, the sides don't meet up at a corner, like an animal corral with the gate left open. So that's not right. Part of the definition of a polygon is that it is closed.

It is a 2-d shape with straight sides and closed, it lies flat in a plane. The last answer is correct.

2 6 + 3 * 4 2 + 7 * - 2 /
Artist 52 [7]

Answer:

26 + 3 x 42 + 7 x -2 = 138

Step-by-step explanation:

Ok bud, first step we must convert our symbols (Makes it easier to solve)

26 + 3 x 42 + 7 x -2

* subsitutes for multiplication.

I recommend using PEMDAS at times:

1 - Parentheses

2 - Exponents and Roots

3 - Multiplication

4 - Division

5 - Addition

6 - Subtraction

Yet again your numbers were spaced out could they be exponents? if so:

3x^{42}+7x+24

Our answer would round to 24 but he equation was not put in a valid or straight forward way.

Determine whether the sides given would form an acute, obtuse, or right triangle. 7, 7, 13
Brut [27]
Let a = 7 , b  = 7, and c = 13. c is always the biggest number.

Acute Triangle is when c^2 \ \textless \  a^2 + b^2

Right Triangle is when c^2 = a^2 + b^2

Obtuse Triangle is when c^2 \ \textgreater \  a^2 + b^2
