Which of the following transformations has the same result as a rotation of 90 degrees clockwise?
2 answers:
Rotation of any geometrical shape by 90 degree, takes the geometrical shape to Next Quadrant.
When we rotate, a geometrical shape , the shape and size of geometrical shape after Rotation does not change.That is the two,geometrical Images (Preimage and Image), before and after Rotation are Congruent.
Now, when we reflect a Geometrical Shape along a Horizontal line,it goes into next Quadrant and when reflection takes place along Horizontal line ,then also, the two Preimage and Image are Congruent.
In both the cases ,only two Adjacent Quadrants are used.
Option B
Reflection of a horizontal line

C
Step-by-step explanation:
First check if the triangle is right.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.
longest side = and (
)² = 12
2² + ( )² = 4 + 8 = 12
Thus the triangle is right → C
Answer:
Range = 45
Median = 75
Step-by-step explanation:
Based on the attached box and whisker plot :
From the plot :
Maximum value = 95
Minimum value = 50
The median value can be obtained from the box and whisker plot. The median value from the plot is ; the green dotted point inside the box :
This point is marked 75.
Hence, median value = 75
Range = maximum - minimum
Range =. 95 - 50 = 45
