This is my firt time to join this group. I need any information about spatial reasoning, geometry reaoning, how to know and how to improve this ability. For...
Can anybody in this group help me to find about measurement of spatial ability and how to measure it? Please, I need your. help. This is my address:...
Hi I have a line from point P1(x1,y2) to P2(x2,y2). I want to draw perpendiculars to P1 and P2. How can I compute every point belonging to any of the...
P1 and P2 lie along the line y=y2, since the abscissae are different but ordinates are the same. The lines perpendicular to the two points are x=x1 and x=x2,...
First, determine the slope of line P1P2, which is (difference of ordinates)/(difference of abscissae)=(y2-y1)/(x2-x1). A line perpendicular to this line will...
You could go to a medical site and ask!!! Carl Adkins ... From: Adi To: geometry@yahoogroups.com Sent: Monday, September 12, 2005 8:14 PM Subject: [geometry]...
Hi, I'm trying to help a young friend in 4th grade with a geometry problem. The problem asks him to draw a quadrangle that has 2 pairs of equal sides but is...
Draw a figure (like a lozenge) with 2 equal sides forming an angle and the other equal sides forming the opposite angle. Luiz Amaral ... From: "Tim Blackwood"...
Hello Luiz, Thank you. :) However, I'm not entirely certain what this means. I've got a picture of a lozenge in my mind and, using your description, it could...
A quadrangle (same as quadrilateral) is a four sided figure, as you probably already know. Draw a straight line for the base. Using a compass with a given...
Hi Tim ... As an alternative to the kite, if you start with a rectangle ABCD then ABDC is a quadrangle looking like a bow-tie and with alternate sides having...
If the opposite sides are equal, the figure is a parallelogram, but see the figure below (it is the best I can draw with text characters). Is it a solution for...
Correction: both pairs of opposite sides must be equal to yield a parallelogram. Carl Adkins ... From: Luiz Amaral To: geometry@yahoogroups.com Sent:...
... Draw one triangle ABC with sides of length AB = 9 cm, AC = 12 cm and BC = 15 cm. Now take the mirror image over the BC side, creating point A' such that...
Hie Everybody, I just read this amazing book called ‘Vedic Mathematics Made Easy’ by Dhaval Bathia (Jaico Publishing House). It has some mind-blowing...
Hi I have a line determined by P1(x1,y1) and P2(x2,y2). I also have a point P3(x3,y3). I need to find the formula of the distance from P3 to the line, and also...
Hi Adi ... You could work out the equations of the two lines and find their intersection point as simultaneous equations. There is also a more general solution...
Hi I have a Point P1. From P1 I draw a line to a point P2 and a line to a point P3. P2P1 and P3P1 forms a semi-closed figure. I need to know if a given point G...
It would take a lot of time and space to explain how to solve this problem. If you have a text on Analytic Geometry, please consult the section on "normal...
Hi, I'm new to the list. I was wondering if someone could tell me what the areas of the three overlapping circles (below) are called. Do they have names? ...
Hi Friends, We are HR Consultants based in Pune. We at the moment have some interesting opportunities going on in some of our client companies wherein they are...
Interesting question!!! Geometric proofs exist for cos(A+B)=cos(A)*cos(B)-sin(A)*sin(B) and cos(A-B)=cos(A)*cos(B)+sin(A)*sin(B). Adding these two equations...
Thanks Carl. Yeah, I knew that the substitutions lead to the sum-to-product identities, but was wondering about a geometric proof. I know you can use the idea...
Damn, it has sure been a while... I just realized today that it's been 12 months since I last went out with a special lady, but I am pretty happy to be...
