Yes. You can even have two triangles with two pairs of sides that are the SAME measure without the triangles being similar.
We can't even begin to do that without seeing the picture.
Without the triangles, no answer can be given.
Triangles without right angles are:- Scalene triangles Obtuse triangles Isosceles triangles Equilateral triangles
It is possible to tessellate a plane with squares, triangles, and hexagons. To tessellate something means to cover it with repeated use of a single shape, without gaps or overlapping.
It is an example of a statement that is presented as a question with minimum of effort. Unfortunately, the minimum effort makes the question meaningless. There is no context given. As a result there are times when the statement within the question would be true and others when it would be false. Without the context it is impossible to tell and so it is a statement with no value whatsoever.
To determine if triangles PQR and XYZ are congruent, we need to compare their corresponding sides and angles. If all three pairs of sides are equal (SSS), or if two pairs of sides and the included angle are equal (SAS), or if two angles and the corresponding side between them are equal (ASA or AAS), then the triangles are congruent. Additionally, if the triangles are similar (AA), they may not be congruent unless their corresponding sides are also proportional. Thus, without specific measurements or angles provided, we cannot definitively conclude congruence.
Assuming you mean by combining 3 of the 4 given lengths. To make a triangle the sum of the two shorter sides must be greater than the third side; thus there are: Without repeats of length: 4 possible triangles. With repeats of length: The smallest length is 4cm with two of this length, the sum is 8cm which is greater than the longest length given (7cm), thus there are no impossible triangles with the given lengths. So there are 20 possible triangles.
Infinitely many. Any triangle inside a quadrilateral can be divided into two without affecting the quadrilateral but increasing the number of triangles by 1. And then one of those triangles could be spilt into two and so on - without end.

it is 3
Because both triangles will be proportionally similar in size and so therefore retaining the same 3 interior angles.
There are many formulae for triangles: Some formulae will calculate sides given angles or conversely. Some will calculate the area. It is not possible to say how you would use a formula without knowing what it is for!
