Answer: The first pair of triangles can be proven congruent by SAS.
Step-by-step explanation:
SAS postulate says that if two sides and the included angle of a triangle are equal to two sides and the included angle of another triangle, then the two triangles are said to be congruent.
In the first pair of triangles the included angle of a triangle are equal to two sides and the included angle of another triangle, therefore by SAS postulate the two triangles are said to be congruent.
In the second figure, the pair of triangles are congruent by ASA postulate not SAS.
In the third figure, the pair of triangles are not congruent by any postulate or theorem [Because there is no SSA rule].
In the fourth figure, the pair of triangles are congruent by SSS postulate not SAS.
Answer:
Step-by-step explanation:
From the graphs attached,
Let the coordinates of the two points given on the black line in the first graph are (-4, 2) and (-1, 10).
When these points have been rotated by 90° about the origin,
Rule for the rotation will be,
(x, y) → (y, -x)
Therefore, coordinates of the image points will be,
(-4, 2) → (2, 4)
(-1, 10) → (10, 1)
Therefore, red line given given in graph (1) and black line (After rotaion of 90° clockwise) in graph (2) will be same.

Answer:
53x - 4 = 30
53x = 30 +4
53x = 34
x= 34/53
I don't see a answer that matches the answer to the problem that you stated. Check problem.
Step-by-step explanation:
No, 5(x-1) expands out to make 5x-5. So 5x-1 and 5x-5 aren’t equivalent.
