Exercise: Constructing similar right triangles with an interior altitude. Three similar right triangles are created by the altitude from the right angle to the hypotenuse of any right triangle. We will use this construction at the end of this section in a proof of the . Pythagorean Theorem. ΔACD ~ ΔABD

Answers may vary. Sample: Two pairs of sides are congruent, but the angle is not included. There is no SSA Congruence Theorem, so you cannot conclude with the information given. 25. ANS: Answers may vary. Sample: Because the two triangles share the side , they are congruent by SAS. Then by CPCTC. 26. ANS: Yes, (in each triangle) 27. ANS:

and it becomes clear that the area of a polygon with one side the hypotenuse of a right triangle is equal to the sum of the areas of similar polygons built on the other two sides of the same right triangle.5 Further examination also shows that areas of circles maintain the Pythagorean relationship when built around the legs of a right triangle ...
