Answer: A rigid transformation preserves both the side lengths and the angle measures of a polygon.

Step-by-step explanation:

  • Rigid transformations are the transformations which does not affect the size  and the shape of figure . The figure doesn't shrink or get enlarger.

Thus, it doesn't affect the side length or the angle measurement of the figure .

There are four rigid transformations such as :

a)reflections, b) rotations, c) translations and d) glide reflection.

Hence, the right statement from all the given statements is "it preserves both the side lengths and the angle measures of a polygon."

If A(1,2), B(5,-4) and (-3,2) are the vertices of a triangle, which statement holds true?
Zigmanuir [339]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The correct option is A.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

The length of different sides are:

AB = \sqrt{(5-1)^2+(-4-2)^2} = \sqrt{16+36} = \sqrt{52}\rm\ units

BC = \sqrt{(-3-5)^2+(2+4)^2} = \sqrt{64+36} = 10\rm\ units

AC = \sqrt{(2-2)^2+(-3-1)^2} = \sqrt{16} = 4\rm\ units

Since the length of all the sides of the triangle is not equal it is a scalene triangle.

Hence, the correct option is A.

HELPPP PLEASE <br> i need a fast reply<br> asking for a friend in need of desperate help :((((
weqwewe [10]

Answer:

y =14

11x = 11*3.5 =38.5

3x+2y = 11x = 38.5

Step-by-step explanation:

The perimeter of a triangle is the sum of all three sides

3x+2y + 11x+y = 91

Combine like terms

14x +3y = 91

The lines mean the sides are equal

3x+2y = 11x

Simplify

Subtract 3x from each side

3x-3x+2y = 11x-3x

2y = 8x

Divide by 2

2y/2 = 8x/2

y = 4x

Substitute 4x in the first equation every time you see y

14x +3y = 91

14x +3(4x) = 91

14x+12x=91

26x = 91

Divide by 26

26x/26 =91/26

x = 3.5

Now we can find y

y = 4x

y = 4(3.5)

y = 14

We know x and y we can find the length of each of the sides

y =14

11x = 11*3.5 =38.5

3x+2y = 11x = 38.5

Looking at the repayment time of peer to peer users how would you assume it compares to that every payment via cash or check? wh
Rina8888 [55]

Peer-to-peer is good for fast payment but is lacking in the transfer of funds security as there is mostly made b/w people with one unknown history or background, most people meeting for the first time, Compared to cash or check which is handled physically. This is further explained below.

<h3>Looking at the repayment time of peer-to-peer users how would you assume it compares to that every payment via cash or check?</h3>

Generally, P2P, which stands for peer-to-peer, is a method of payment that enables users to make purchases without needing to have access to their financial institution's account information. The transfer is completed quickly and, in most cases, at no cost. There is a generational divide in terms of adoption, but the vast majority of Americans today make use of mobile payment applications.

In conclusion, Peer-to-peer transactions are typically conducted between people who do not know each other's histories or backgrounds, and the majority of transactions involve people who are meeting for the first time. This makes peer-to-peer transactions less secure than cash or checks, which are physically handled. Peer-to-peer transactions are useful for making payments quickly.
