One line can divide a plane into two regions. Two lines can divide a plane into four regions. Three lines intersecting at a point can divide a plane into six regions, but you can get more regions than that if the lines don't intersect at a single point. My question for you...

Help with triangle
I need help with these: Triangle LMN has vertices L(-6,5), M(-4,-3), N(-2,4). Find the coordinates of the vertices of its image after it is reflected over the x-axis and then translated by (-3,0) a. L(-9,-5), M(-7,3), N(-5,-4) b. L(-6,-5), M(-4,-3), N(-2,-4) c. L(-5,-6), M(-7,...

There must be a relationship (formula) between the lengths of the sides of a Right Triangle and the angles opposite these sides. Help Please. Mike. Look at the law os sines or cosines. Law of sines a/sin(A) = b/sin(B) = c/sin(C) Law of cosines a2 = b2 + c2 - 2bc cos(A) b2 = c2...

Congruence-creating a triangle
Three segments are given. I need to draw one segment with the same length as any one of the given segments. Then take the measure of another given segment with my compass and draw a cirlce of that radius from the endpoint of my first segment. The question is: 1. What is true ...

If one angle and two sides of a triangle are given, how to find the third side? This is for solving a 9th grade geometry problem of finding the distance from earth to venus You can use a standard formula for the side of the triangle that must be mentioned somewhere in your ...

corollary to isosceles triangle theorem
how to prove 1)the measure of each angle of an equilateral triangle is 60. 2)the bisector of the vertex angle of an isosceles triangle is the perpendicular bisector of the base. Thanks. 1) The angles in any triangle have to add up to 180 degrees, right? 3 x 60 = 180 2) ?? 2. ...

math right triangle
the hypotenuse of a right triangle is 1 inch longer than one leg and 8 inches longer than the other. Find the length of each side of the triangle. Let l1, l2 be the legs. l1^2 + l2^2 = h^2 but h= l1+1 and h= l2 + 8 solve these for l1, l2, put them in the first equation and ...

I am having trouble understanding dipole moments. I can't figure out why that a tetrahedral CF4 molecule, trigonal planar SO3 molecule and a octahedral H2SF4 molecule are non-polar while a H2CF2 is polar? I hope I explained that well and thanks! For CF4, think of it this way. ...

An isosceles triangle is a triangle that has two equal sides. Find AB, BC and AC. Determine if the triangle is isoseles or not based on the lengths of the three sides. can someone show me how to solve?please The triangle is isosceles if AB = BC, or BC = AC, or AB = AC. Without...

construct a triangle
How can I construct a triangle ABC with vertices A(-4,2), B(4,3), C(1,-3). what are the angles in order from least measure to greatest measure Since you will have to use trigonometry to find the angles, surely you must know how to plot points. take the slope of each of the ...

It helps to draw a picture. The sides of the triangle are congruent, and the angle is also congruent, so by SAS (Side-Angle-Side) Congruence, they are also 110 yards apart.

Explain how the triangle similarity postulates and theorems are alike and how they differ from triangle congruence postulates Name something with a height that would be difficult to measure directly. Describe how you could measure it indirectly
Friday, January 25, 2008 at 12:45am by help plz
Similarity theorems and postulates involve matching either angles only, or the ratios of corresponding side lengths. Congruence theorems and postultates invove actual lengths of corresponding sides. See http://www.mathwarehouse.com/geometry/similar/triangles/similar-triangle-...

math- Triangle facts
(1) A triangle is called an isosceles triangle if it has two sides with equal lengths. Consider an isosceles triangle ABC with AC = CB. Then side AB (i.e. the side that is not equal to the other sides) is called the base side. The angle opposite the base side is called the ...

Determine whether this is a right triangle vertices: G(1, -1) H(5, 0) and J(3, 8) Should I use distance formula to find the sides and use Pythagorean theorem to prove it? Or is there another method? Thanks.
Friday, February 15, 2008 at 11:22am by Jen
The easiest way is to use the distance formula for points in the (x,y) form. Use the formula 3 times. You have triangle GHJ. Use the formula from point: G to H H to J G to J Only then will you be able to tell if triangle GHJ is a right triangle or not.
