Question

Mei has a large triangular stone that she wants to divide into four smaller triangular stepping stones in a pathway. Explain why cutting along each midsegment creates four congruent stepping stones.

Answer 1

@eSpeX do you know this?

Answer 2

use mid-point theorem

Answer 3

can you explain that to me please?

Answer 4

the theorem goes more or less like this that the line joining the mid points of any two sides of the triangle is parallel to and half of length of the remaining side..
i hope this will help u

Answer 5

oh man i so just got lost.

Answer 6

like i need to know why if i cut the triangle it will make 4 congruent triangles of the same triangle?

Answer 7

As @matricked explained, each triangle has three midsegments and each is parallel to the third side. So by joining the midpoints you are cutting the triangle in half and there is most likely a test or proof you could use to show how they become congruent.

Answer 8

it doesnt say a proof it just says explian cuting it lol so you just exsplained it thank you so much i have 3 more yes!

Answer 9

Looks like a parallelogram, is there a question?

Answer 10

you got it right :)

Answer 11

WOO HOO!

Answer 12

For a regular n-gon:
a. What is the sum of the measures of its angles?
b. What is the measure of each angle?
c. What is the sum of the measures of its exterior angles, one at each vertex?
d. What is the measure of each exterior angle?
e. Find the sum of your answers to parts b and d. Explain why this sum makes sense.

Answer 13

So what is a n-gon? Any type of regular polygon?

Answer 14

i have no clue this wasnt even in the book.

Answer 15

Why yes it is, it is a polygon with 'n' sides. So it is a representation of all polygons.

Answer 16

omg that is too much!

Answer 17

You will most likely find the formulas in your book, the measure of an internal angle is \[(1-\frac{2}{n})\times 180\]

Answer 18

where 'n' is the number of sides.

Answer 19

it just says n-gon not all poly gons :/

Answer 20

is this it?
N-gon
Ext angle = 360/ N-gon
Int angle = 180 - 360/N-gon
Ratio is 360/N-gon : 180 - 360/N-gon
Ratio is 360/N-gon : (180*N-gon - 360)/N-Gon
Ratio is 360 : 180*N-gon - 360
Ratio = 360 : 180(N-gon - 2)
Ration = 2 : 1*(N-gon - 2)
Ratio = 2: (N-gon - 2)

Answer 21

Looks like it.

Answer 22

Find the midpoint of each side of the trapezoid. Connect the midpoints. What is the most precise classification of the quadrilateral formed by connecting the midpoints of the sides of the trapezoid?

Answer 23

@eSpeX do you know this one?

Answer 24

If I understand this correctly you are basically cutting the shape in half, horizontally. If that is the case then you are just creating two trapezoids out of one.

Answer 25

do you know the midpoints?

Answer 26

I assume it is similar to that of a triangle, center of the sloped sides since the midsegment is the line that is parallel to the two parallel sides.

Answer 27

Seems they call it a median rather than a midsegment.
