3,4,5 and 5,12,13 are two possibilities.
No because then it would have 6.5 sides which is impossible
5cm, 5cm, and 5cm could represent the lengths of the sides of an equilateral triangle, or might indicate the length, width, and height of a cube.
Supplementary is what makes 180 degrees. 180-76=104
It can't.
Matrices are used in most scientific fields. They are usually used to represent and manipulate a number of measures simultaneously.For example, they are used to represent and solve systems of simultaneous equations. In basic mechanics could represent the coordinates of the location of particles or specific locations on a rigid body. Joint probability distributions - for n variables - are represented, using matrices, as surfaces in n+1 dimensional space.
It could be a right angle. It has three different side lengths, but not always will the angle measurements be different. Evidently, one angle always measures 90 but the other two could either be the same or different.
Those wouldn't be angle measurements, they would be sides. A triangle could be constructed with sides of those lengths.
The answer will depend on the figure, the type(s) of symmetry and what information about is is given.
A rectangle, or could be a square if lengths are the same.
Divide the shorter leg by the longer, then look it up on the tangent table in any trigonometry text. This will give you the size of the smallest angle.
Those three numbers could be the lengths of the sides of a right triangle,because the squares of two of them add up to the square of the third one.
If its a right angle triangle then its side lengths could be 3, 4 and 5
No.

Congruent angles are of the same size as for example 85 degrees is congruent to 85 degrees
We need one more angle to answer. We know one angle is 90 degrees. The other two could both be 45 or one could be 30 and one could be 60 etc. In all those cases, the sides are different lengths.
