Yes, AAA is a way to show that triangles are similar.
Note, however, that AAA is not a way to show that triangles are congruent.
Without seeing the picture, I can't tell what's already known to be congruent, so there's no way I can figure out what 'else' is needed.
The interior angle is the angle formed from two sides of a nth-sided polygon. Because the polygon is regular, all angles formed from any two sides of the polygon are equal. It can be proven, but I won't attempt to, that to find the amount of sides, you use 180-[interior angle], and divide the answer by 360. In this case, 180-156=24, 360/24= 15, thus the polygon has 15 sides. One way to prove it is to imagine the polygon and divide it into isosceles triangles. But I won't go there.
A left angle triangle, also known as a right triangle, is a triangle in which one of the angles measures exactly 90 degrees. This type of triangle is characterized by one right angle and two acute angles. The side opposite the right angle is called the hypotenuse, while the other two sides are known as the legs. Left angle triangles play a significant role in trigonometry and are fundamental in various mathematical and geometric applications.
If you are talking about the common triangle puzzle, then there are 27 triangles. There are 16 one-cell triangles, 7 four-cell triangles, 3 nine-cell triangles, and 1 sixteen-cell triangle. There is a link to the pic for you also. _______________________________________________________________________ The answer in a two dimensional way would be 27. However, if you take into account that each triangle can be turned three ways, then you can understand that there are actually 81 triangles in all. THen you could ask the question, how many triangles can fit in this space (i.e. the picture)? The answer is the first level of infinitely many, or Aleph zero. This would be by finding the midpoint of each side of the all the 1- cell triangles and creating a new triangle.
It is a reference to two triangles, ABC and DEF which may or may not be related in any way.
Yes.
Triangles are congruent if all three sides in one triangle are congruent to the corresponding sides in the other.When two triangles have corresponding sides with identical ratios, the triangles are similar.Of course if triangles are congruent, they are also similar.
They are both closed figures
One way to separate triangles into smaller triangles is by drawing a line segment from one vertex to the midpoint of the opposite side, creating two smaller triangles within the original triangle. This technique utilizes the concept of midpoints, segments, and vertices. Additionally, you can bisect an angle, drawing an angle bisector to form two triangles that share a common vertex. Each of these methods maintains the properties of triangles and ensures that the new shapes are also triangles.
Yes, it is possible to divide a square into obtuse triangles. This can be achieved by drawing lines that connect points on the square's sides or corners in such a way that the resulting triangles have one angle greater than 90 degrees. For example, by connecting a vertex of the square to points along the opposite side, you can create triangles that each have an obtuse angle.
you just have to hack the system and get the answers that way
Two right-angle triangles can be put together to form a square. Proof is to draw a square, and then draw a line from one corner diagonally to another corner passing through the middle of the square. You now have a drawing of two triangles forming a square.
The proof is fairly long but relatively straightforward. You may find it easier to follow if you have a diagram: unfortunately, the support for graphics on this browser are hopelessly inadequate.Suppose you have a rhombus ABCD so that AB = BC = CD = DA. Also AB DC and AD BC.Suppose the diagonals of the rhombus meet at P.Now AB DC and BD is an intercept. Then angle ABD = angle BDC.Also, in triangle ABD, AB = AD. therefore angle ABD = angle ADC.while in triangle BCD, BC = CD so that angle DBC = angle BDC.Similarly, it can be shown that angle BAC = angle CAD = angle DCA = angle ACB.Now consider triangles ABP and CBP. angle ABP (ABD) = angle CBP ( CBD or DBC),sides AB = BCand angle BAP (BAC) = angle BCP (BCA = ACB).Therefore, by SAS, the two triangles are congruent.In the same way, triangles BCP and CPD can be shown to congruent as can triangles CPD and DPA. That is, all four triangles are congruent.
They can be constructed in more than one way. They have fractional dimension. They are self-similar. They are constructed by removing small triangles from a big triangle.
90
No. Equilateral triangles have 60o angles. There is no way to build a right-angle triangle with sides of equal length.
One way is they both are triangles and have 3 sides.
