prove the converse of the pythagorean theorem using similar triangles. the converse of the pythagorean theorem states that when the sum of the squares of the lengths of the legs of the triangle equals the squared length of the hypotenuse, the triangle is a right triangle. be sure to create and name the appropriate geometric figures.

let acb be a triangle where segment ab is labeled c, segment bc is labeled a, and segment ca is labeled b. using a compass and straightedge, construct right triangle xzy with legs xz and zy congruent to legs ac and cb , respectively. let xz be labeled y, zy labeled x, and yx labeled z. therefore, y = b and x = a. because triangle xzy was constructed as a right triangle, x^2 + y^2 = z^2 by the by a^2 + b^2 = z^2. according to the given information, a^2 + b^2 = c^2. by thec^2 = z^2. use theto take the square root of both sides of the equation to result in the equation c = z. by the triangles acb and xzy are congruent. consequently, by triangle acb is a right triangle.

3. annie walks 15 feet away from her house and places a mirror on the ground. she backs 4 feet away from the mirror so that she can see the tip of the roof. annie’s eyes are 5 feet above the ground. annie and the house are both perpendicular to the ground. the angles between the top of the house, the mirror, and the ground and between annie’s eyes, the mirror, and the ground are congruent as shown in the image:

what is the height of the house? show your work and explain your reasoning in complete sentences.

the triangle formed by the person, the mirror, and the ground is similar to the triangle formed by the house, the mirror, and the ground. the distance between the mirror and the person is 4 feet. the distance between the mirror and the house is 15 feet. the distance between the ground and the person’s eye level is 5 feet. let x = the height of the house.
