Find the perimeter of a rectangle Input: two numbers l and b
Output: result of l*b

Algorithm steps
Step 1: start
Step 2: declares variables l, b,result
Step 3: Write “Enter the length of the rectangle”
Step 4: read l
Step 5: Write “Enter the breadth of the rectangle”
Step 4: read b
Step 5: calculate perimeter of rectangle result = 2(l+b)
Step 6: Display “The perimeter of the rectangle is” +result
Step 7: stop

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

do have an equation or graph or
