Hello Roy, here's a solution: Let the apex angles of the three isosceles triangles be 2x, 2y, and 2z. Then
by elementary trignometry, the bases of the...
Squares are erected outwardly on the sides of a quadrilateral. Show that the two lines joining the centers of opposite squares are perpendicular and the same...
Simple program: just drag & drop a picturebox into your object window, then copy & paste the code below into your code window. You may have to fix the code a...
... Because, if you project a circular orbit with constant angular speed over a plane that is rotating with the same angular speed, the resulting figure _is_ a...
I still don't understand. Every textbook I've found has the same matrices for rotation around the x-, y-, and z-axes. But the program I wrote doesn't work...
Here are 2 questions which none of the students in our institution could solve : D is a point on the circumcircle of triangle ABC in which AB = AC such that B...
Does anybody know how to solve this problem? Given the 3 direction vectors emanating from one apex(P0, at the origin), d1,d2,d3, and the corresponding lengths...
Hi! I just joined this group and I have a problem, which I want you to help me solve. I have to prove that in a triangle ABC, if the angle bisector of A meets...
hi, i have a spirolateral problem that i was wundering if ne1 cud help me solve it. find a spirolateral that has at least 5 "leaves" or the 5 repeating...
After beating my head against the wall repeatedly, I decided to come online to find help with my Trig homework. I'm Allison, and currently taking Trig at my...
I'm stuck on the following problem: sin(a) - csc(a) = -cos(a)cot(a) Here is what I've done: On the left side I get: sin(a) - 1/sin(a) --> * both by sin(a) to...
sin(a)-csc(a)=?-cos(a).cot(a) sin(a)-(1/sin(a))=-cos(a).(cos(a)/sin(a)) Multiple both side with sin(a) sin^2(a)-1=-cos^2(a) Multiple both side with -1 ...
Hello ! To Every one ..... Well i need to know about shortest distance b/w two Stright lines .... plz help me also tell me formulas and i'll be kindfull if u...
... What do you mean? You have two lines in a 3D [or more] space, and you want to find the distance between them? Such as line1 = { P | P = A1 + B1 t1 } and ...
I need some help on my hyperbolic geometry... see if you guys can help me out 1) In hyperbolic geometry, prove that given a line l and a point P not on l,...
Find the equation of the set of points P (x, y) which satisfy the given condition. From the equation sketch the graph. P (x, y) is equidistant from the point...
Welcome Is it true that if a point P is in a polygon ABCD then angles: APB+BPC+CPD+DPA>360 ? If yes, how will look the proof? Thank you for any answer Best...
This is true, only if, one of the internal angles of the polygon is a reflex angle, i.e. the polygon is boomerang or "Starfleet Badge" shaped, and one of the...
Hello Thanks for the answer. I have thinked about it, but I still don't know how to proof that three of the angles at p are equal to 360 deg. Can you give me...
Hello Adam, Here is an example of the special case where the sum of the four angles is greater than 360 deg. Construct the following diagram with ruler, pen...
