William is in the middle of swimming in a ten-mile race. He swims at a steady speed, and then slows down, stops to eat
Swims faster to get back in the race, and returns to a steady speed. He later stops for water, and then again swims faster to
get back in the race. Which graph best represents the situation?

r and t.

both are 64 degrees.

the square root of 16 is 4.

4*4 = 16

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
