isosaleez triangel, base=6 & both base angels=45 deg

That impli top angel=90 deg.

draw vertikal line from middel av base...it go thru top point

this triangel hav base=3.

hite=base*tan(45 deg)=base=3

so triangel points at (0,0), (6,0), & (3,3)

area=3*6=18

You cannot "construct"  a triangle with a length given since in a true construction you can only use straightedge (not ruler) and compass.  You could do this if you could copy the length of the base.  "Construction" in geometry has a Euclidean meaning and terms in math, of all disciplines, should not be used loosely.  Why not use the term "draw" or equivalent?   Thanks
