Grade 8 Pythagorean Theorem and Applications CCSS: 8.G.B.6
Write the letter "D" at the point where the altitude meets line AC.

Given: Triangle ABC is a right triangle; $angB$ is a right angle; line BD is perpendicular to AC

Which reason explains the following:

$(AC)/(BC) = (BC)/(DC); (AC)/(AB)=(AB)/(AD)$

1. though a point outside a line, there is exactly one line perpendicular to the given line
2. given the altitude of a right triangle, the legs are the geometric mean of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg
3. when the hypotenuse and a leg of a right triangle are congruent to corresponding parts of another right triangle, the triangles are congruent
4. the sum of the side lengths of any two sides of a triangle are greater then the length of the third side
