Answer to Problem 4PSA

  JM/MK is equal to HJ/JK.

Explanation of Solution

Given information:

  HJK is a right angle.JM¯ is an altitude.

Formula used:

The below properties are used:

An altitude forms perpendicular lines with sides.

Perpendicular lines form right angles.

Right angles are congruent.

Corresponding sides of similar triangles are proportional.

Proof:

  Geometry For Enjoyment And Challenge, Chapter 8.4, Problem 4PSA

It is given that,

  HJK is a right angle.JM¯ is an altitude.

An altitude forms perpendicular lines with sides.

  JM¯HK¯

Perpendicular lines form right angles.

  JMK is a right angle.

Right angles are congruent.

  JMK HJK

By reflexive property, we get

  K K

By AA similarity rule, we get

  ΔJMK~ ΔHJK

Corresponding sides of similar triangles are proportional.

  JM/MK = HJ/JK
