Construction of a triangle given a, c, and h(a)
To see a GSP sketch click here.

Given the following segments a, c, and h(a), construct a triangle:

Begin the construction by constructing a line upon which to build the triangle. Construct a perpendicular to this line and call the intersection point P. Now copy h(a) onto the first line constructed and call its intersection point Q.

Now from Q strike an arc on the line perpendicular to the line on which it lies and call its intersection point R. Then from R copy the side "a" onto the line incident to R and call its point S.


Now draw the segment SQ.

Thus, the triangle is constructed.
