4. Plot a polygon by selecting the polygon tool. Plot a point on the first vertex and then
on the second vertex, until the graphing function connects the two vertices with a line
segment. Continue plotting the vertices in order until you return to the first vertex.
A triangle is displayed in the coordinate plane. Plot the transformed triangle when
translated 5 units down and 2 units to the right.

b.-4 units

all you   do is count how many times you move

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
