Geometry Homework Help.....

I SERIOUSLY need some help, I'll post the questions and if anyone can help me, it would greatly be appreciated....


1.)Use the forumal A=1/2bh for the area of a triangle to develop formulas for the area of (a) a paralleogram, and (b) a trapezoid.


2.)Find the area and the perimeter if each polygon.
a.)square with radius 1
b.)regular hexagon with apothem 1

3.)Iaminge a regula polygon with many sides-20, 50, or even 100.
a.)What does such a figure approximate?
b.)If the polygon were inscribed in a circle, explain the relationship between the apothem (a) and the radius (r), and between the perimeter (p) and the circumference (C)
c.)Discuss the connection between the area of the polygon, A = 1/2ap, and the area of the circle, A = pie (r) squared

I guessed my way through geo...and still passed with a A-...it's not that hard...just learn the formulas and B.S. your way through the rest...and if it's a test I'm not going to help you...

Alright, I'll try it your way. So far I tried working out the first one, and since you can tessellate two triangles, I figured you could make a parallelogram out of it. So what I came up with was to multiply the base and the height times 2, and then multiply the 1/2 by two, but that makes one whole, so I didn't know if that was right

@-OTC, Well, over here we learn it at 10 grade, but I'm learning it at 8th...stupid advanced placment >.>

The first one

It says to form an eqaution for a paralleogram, and what I posted above is the farthest I thought up of. The only problem I had was whether or not to multiply the 1/2 by 2 like I did with the base and the height

c.)Discuss the connection between the area of the polygon, A = 1/2ap, and the area of the circle, A = pie (r) squared
1) a. a parallelogram is basically two triangles put together, so its just b x h

b. an trapezoid is kind of like a triangle, but the top has a side too, so its 1/2(b1 + b2)h (b = bottom base and top base)

2)a. if the square has a radius of one (i hope u know what it looks like drawn, cuz then this wont make sense) u can draw a line from the center of the square to one of the corners on the same side where the radius hits, forming a right triangle, then using the 30-60-90 triangle rule, solve for the length of the side of the triangle that would be the square, then double it cuz the lenght u found is only half of the square, then use the length found to find the area and perimeter

b.same principle as in 'a', but the triangle will be different, so a diff rule will need to be used to find the 1/2 length of one of the sides of the hexagon (which would be the side of one of the triangles)

3) meh, im to tired from typing to explain that one, maybe later

let's do this way is easier.. u don't have to multiply it.. since is 1/2 that means they asking for the half of the number
for example:
my triangle have 1 leg is 2, 1 leg is 6, and the base is 5
and the forumlar is A=1/2bxh

so i would find out the half of 2 (which is one) then multiply by 5 and muptiply by 5.. then equal the the answer

Thanks Inu, I get no.2. The problem with no.1 is that it says to use the triangle formula for a parallelogram, so I think that b x h is too simple, there must be a catch.

EDIT: Wait sec lilx I'm still reading it lol.

EDIT:Alright I get it so far, but my mom is making me go with her to the pharmacy, I'll have to thank you very much for your help lilxv. but I have to leave. thanks ^^

no, no catch, a parallelogram is in essence, 2 triangles put together, so there is no 1/2 b/c ur doubling the triangle...
