## # Squares Inscribed in a Right Triangle Note:  There are five related by different problems here.

Figure 1 and Figure 2 each show a square inscribed in a right triangle. Assume the triangles, both labeled ABC, are congruent, or two copies of the same triangle.

1. Given any right triangle with sides of length a, b, and c, as above, determine the two constructions to inscribe these squares in the right triangle.

Create GSP sketches for the two constructions using congruent right triangles with legs of length a and b.

Do you have alternative constructions to those suggested in the hints? Here is a construction showing both squares in the same triangle. An altitude h to the side of length c is also shown.

2a. Show that the length of the side s of a square instcribed in ANY triangle with one side along a base is one-half the harmonic mean of that base and the altitude to that base.

2b. Show a geometric construction for the inscribed square in ANY triangle with one side along a base.

See Square Inscribed along a base of any Triangle

3. Which of the two squares has the largest area? For example, here are two expressions for the area of triangle ABC and each can be solved for the length of the side of one of the squares in terms of a, b, c, or h.

Will the largest inscribed square always be the same orientation for any right triangle? That is, will one of the two squares always be the largest?

HINT:  Write an expression for and evaluate to see if this this expression is always positive, always negative, equal, or not determined.

4.  Consider a geometric demonstration regarding the relative sizes of the two inscribed squares.   To accomplish this, construct an auxilliary right triangle with legs of length h and c on our right triangle having legs a and b,  h and c being the altitude and the hypotenuse of the original triangle.
