What is pythagreom theroem?
it is used in triangles and it is a2 + b2 = c2a being the short legb being the long legc being the hypotenuse
How many triangles can a 20-gon be made into?
20 isosceles triangles with each base being a side of the 20-gon, and the opposite vertices at the center of the polygon.
Can any two triangles be joined to make a rhombus?
No. A rhombus has all four sides of equal length. To split a rhombus into only 2 triangles, it must be split along a diagonal; which means that 2 of the sides of one of the triangles must be the same length as the sides of the rhombus, which being equal mean the triangles must be (at least) isosceles - scalene triangles will not work. Further, as the diagonal will be a common length to each of the triangles (the length of their third sides), it will form the base (ie the side opposite the vertex between the sides of equal length) of the isosceles triangles, and so the triangles must be to congruent isosceles triangles. If the diagonal has the same length as the side of the rhombus, then the two congruent triangles will be congruent equilateral triangles.
DoTriangles have a 90-degree angle?
No. A triangle may have a 90-degree angle, but not all triangles do. The only requirement for being called a triangle is that it is a closed figure with 3 sides.No. A triangle may have a 90-degree angle, but not all triangles do.

Which postulate identifies these triangles as being simliar?
To determine if triangles are similar, we typically use the Angle-Angle (AA) postulate, which states that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar. Additionally, the Side-Angle-Side (SAS) similarity postulate and the Side-Side-Side (SSS) similarity postulate can also be used, but AA is the most common and straightforward criterion.
Is it possible for two triangles to have two pairs of sides that are proportional without the triangles being similar?
Yes. You can even have two triangles with two pairs of sides that are the SAME measure without the triangles being similar.
What is the factor being tested in an experiment?

Can postulate become a canon in episcopal church before being ordained to the priesthood?
No.
What the forgetful professor said about the letter he forgot to mail?
postulate!... this is a "play on word" mathematical riddle... a postulate is really a geometric term, but it is being used as "post you late."
Where does the formula for the sum of interior angles of a polygon come from?
Euclid parallel postulate can be interpreted as being equivalent to the sum of the angles of a [plane] triangle being 180 degrees. It is quite easy to prove that a polygon with n sides can be divided into n triangles. Putting the two together, you get the formula for the sum of the interior angles of a polygon.
What you the difference between a postulate and a theorem?
A postulate is something that is accepted as true without proof. A theorem, on the other hand, is something that has been proven and is now being accepted as true.
Do all triangles have right angles?
No. Only right triangles do, and not all triangles can be right triangles. Equilateral triangles, for example, are always 60°-60°-60°. Isosceles and scalene triangles can be right triangles; all isosceles triangles have the additional useful property of being able to be split into two right triangles.
