Answer:

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

The acute angle is the small angle which is less than 90°. If you choose the larger angle you. will have a Reflex Angle instead: The smaller angle is an Acute Angle, but the larger angle is a Reflex Angle.

In geometry, there are five types of angles. An obtuse angle is greater than 90 degrees but less than 180 degrees. An acute angle is less than 90 degrees, A right angle is exactly 90 degrees. A straight angle is exactly 180 degrees, and a reflex angle is greater than 180 degrees.

Part (a)

The angles would stay the same. This is because similar figures keep the same shape, but the size will shrink or grow.

A real world application is to simply move your head closer to the page and the figure will appear to get larger. The angles themselves stay the same but the side lengths will get larger.

====================================================

Part (b)

While the angles stay the same under a dilation operation, the side lengths do not. As the instructions state: "The side lengths are 3 times longer" (paraphrased).

So we multiply each side length in the diagram by 3

DE = 3*JK = 3*4.5 = 13.5
EF = 3*KL = 3*3 = 9
FG = 3*LM = 3*2 = 6
GD = 3*MJ = 3*2.5 = 7.5

Refer to the diagram below. I've used the resize feature to enlarge the image to make figure DEFG

Answer:

1/2 = 3/6

1/3 = 4/12

1/5 = 2/10

1/4 = 5/20

Step-by-step explanation:

To make equivalent fractions, you need multiply by 1. A number divided by itself is 1.

1/1 * x/x = x/x = 1

1/2 = 3/6

$\frac{1}{2} * \frac{3}{3} = \frac{3}{6}$

1/3 = 4/12

$\frac{1}{3} * \frac{4}{4} = \frac{4}{12}$

1/5 = 2/10

$\frac{1}{5} * \frac{2}{2} = \frac{2}{10}$

1/4 = 5/20

$\frac{1}{4}*\frac{5}{5}=\frac{5}{20}$

Hope this helps :)

Have a great day!

Using a commen denominator to order fraction, please help...

Aleks04 [339]

You have to find the least common denominator then compare numerators after you determine the factor by which you must multiply your denominators by in order to make them equal. Then apply the same factor to the numerators.
