Fully explain two different ways you could use transformations to go from shape a to shape B
1 answer:
Answer:
1. rotation 180 degrees to the right (or left), 2. reflect shape A over the horizontal line at the bottom of the shape, then reflect the result over the short vertical line that goes through the point where the shapes meet.
Step-by-step explanation:
See the attached image. Method 2 calls for two reflections, one across the red line, the second across the yellow line.
P.S. I added an image that shows the shape reflected across the red line. Finally, flip THAT horizontally.

Answer:
There's no specific formula to find the square root of a number, however we can find the square root of a number by the following methods:
i) By Prime Factorisation
ii) By Long Division
iii) By Repeated subtraction method
<h2><u>✏ By Prime Factorisation: </u></h2>Step I: Obtain the given number.
Step II: Reduce the given number into prime factors by successive division.
Step III: Now make pairs of prime factors in such a way that both the factors in each pair are equal.
Step IV: Take one factor from each pair and find the product of these factors.
Step V: The product obtained by multiplying the factors is the required square root.
<h2><u>✏ Long Division:</u></h2>Step 1: Firstly, we place a bar on every pair of digits starting from the unit digit. If the number of digits in it is odd, we put a bar on the single-digit too.
Step 2: Now we find the largest number whose square is less than or equal to the 1st number.
Step 3: Now we bring down the next bar number.
Step 4: For new divisor, we add the divisor & quotient.
Step 5: Number taken is the product of a new divisor and this digit is equal to or less than the new dividend.
<h2><u>✏ Repeated subtraction method: </u></h2>In this method, the given number is subtracted by 1, 3, 5, 7,… at every step till you get zero at the end. The number of steps in the solution is the required square root.
