Use the Polygon tool to draw the image of the given quadrilateral under a dilation with a scale
Nataly [62]

Answer: See the picture attached.

Step-by-step explanation:

A Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case we know that the scale factor is:

scale\ factor=\frac{2}{3}

Since:

0

It is a Reduction.

You can identify that the vertices of the quadritaleral are:

(-3,0),(-9,-3),(-6,-9),(3,-6)

 So you need to multiply the coordinates of eac vertex by \frac{2}{3} in order to get the coordinates of the image.

Then, you get:

(\frac{(-3)(2)}{3},0*\frac{2}{3})=(-2,0)\\\\(\frac{(-9)(2)}{3}),\frac{(-3)(2)}{3})=(-6,-2)\\\\(\frac{(-6)(2)}{3},\frac{(-9)(2)}{3})=(-4,-6)\\\\(3*\frac{2}{3},\frac{(-6)(2)}{3})=(2,-4)

Now you can plot the points and draw the image of the given quadrilateral.

See the picture attached.

Hayden is creating triangles using plastic straws cut to various lengths for the sides. Which set of straw lengths can he use to
balandron [24]

Answer:

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.

A scalene triangle is a triangle in which all the three sides of the triangle have different lengths hence, all the angles of the triangle also have different lengths.

Therefore the set of straw lengths that can be used a scalene triangle must have different lengths, for example:

5, 7 , 8
