This is how a triangle is equal to one another, SAS is side angle side, AA is angle angle, ASA is angle side angle, and SSS is side side side, yours looks like AA but I might be wrong. I believe it is AA, so if you have no clue just go with AA
        
                    
             
        
        
        
 The chances will be : 3 and 6 and 4 and 5
The probability of getting a sum of 9 would be 2/9

Answer:
B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90  clockwise
Step-by-step explanation:
This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).
 
        
             
        
        
        
Given:
The matrix multiplication

To find:
The order of resulting matrix.
Solution:
We know that, if order of first matrix is  and the order of second matrix is
 and the order of second matrix is  , then the order of these two matrices is
, then the order of these two matrices is  .
.
We have,

Here, the order of first matrix is  and the order of the second matrix is
 and the order of the second matrix is  . So, the order of the second matrix is
. So, the order of the second matrix is  . It is also written are 2 by 1.
. It is also written are 2 by 1.
Therefore, the correct option is A.
