Question

FLASH CARDS Is this the only diagonal in this concave hexagon?

Answer 1

Answer 2

Answer 3

You can draw more diagonals in it by joining vertices which are not adjacent

Answer 4

Would this be too much? does it make sense?

Answer 5

they are okay as long as you do not join two adjacent vertices to form a diagonal, which would result in over writing a side of the polynomial anyhow.. although I'm unsure whether the diagonal can go out of the polynomial or not (in case of concave polynomials)

Answer 6

Edit: Yes you can have diagonals that go outside the polynomial as well

Answer 7

Ok. and can i ask you a few more questions?

Answer 8

np

Answer 9

The third point has to make this an isosceles right triangle and no matter how much i try i cant get it right

Answer 10

Do you have to solve this question on paper with the help of a compass or with calculator?

Answer 11

Nop no calculator involved. But it doesnt say so i guess mayb i compass would work

Answer 12

but i wouldnt know how to use a compass on this problem

Answer 13

Take a compass and set it to a specific length, preferably shorter than the 7 units line given in the diagram. Set it, turn by turn, on each end of the line and draw an arc with it. The two arcs will intersect at a point. This point completes an isosceles triangle, but not necessarily a right angled triangle. For getting a right angled triangle, increase or decrease the length of the compass and check with the pythagorean theorem

Answer 14

omg there is an extremely simpler way to do that, as compared to the one I described above

Answer 15

EM is 7 units in length. let it be one leg of the isosceles triangle, and the other leg should have 7 units length too. further, since it is a right triangle, the two legs of the isosceles trianlge should be at 90 degrees to each other. So from point E or M just take a 7 unit line perpnedicular to EM

Answer 16

this will give you the two of the points you need: (3, 4) and (3, -3)

Answer 17

Sorry i didnt ever reply OS was losing connection with me

Answer 18

thats okay the same was happening on my browser

Answer 19

can you help me with some geometry flashcards? like for example this one idk what to say about it

Answer 20

The three lines are the angle bisectors of the triangle, and they meet at point P. P thus becomes the in center of the triangle

Answer 21

and i can also say that it has three pairs of congruent acute angles and that must be all there is to say

Answer 22

How about this one? I think its trying to ask how would i solve for x? but i dont know

Answer 23

The question, from the diagram, seems to be "Find the measure of an internal angle of a regular pentagon."

Answer 24

would it be 180(n-2) or 180(n-2) divided by 2?

Answer 25

use the formula for sum of interior angles of a polygon 180(n - 2) to find the total sum of the angles

then, since it is given that the pentagon is regular, which means that its sides are equal, and consequently its angles as well, so divide the total sum by 5 to get the measure of each angle. this is really simple

Answer 26

But since there is no numbers do i actually try to solve or just write an explanation?

Answer 27

There is only one number you need to solve the problem, the number of sides in the regular polygon which is given by 'n' in the formula

Answer 28

so you do need to solve it using that formula

Answer 29

Kay i got it. 108 degrees

Answer 30

These are called consecutive interior angles right ?

Answer 31

Yes and also co-interior angles

Answer 32

For this one im really confused

Answer 33

It is an identity: x is twice of y
btw please post the in a new question :) .. the scrolling down becomes quite hard!

Answer 34

Lol sorry I will
