Answer to Problem 25RP

The perimeter of the given triangle is 30 cm

Explanation of Solution

Given information:

One side of the triangle is 4 cm shorter than a second side

The ray bisecting the angle formed by these sides divides the opposite side into 4 cm and 6 cm segments

Formula used:

Perimeter is sum of sides

Ratio of corresponding sides of the triangles are equivalent

Calculation:

  Geometry For Enjoyment And Challenge, Chapter 8, Problem 25RP

In the figure,

Let BC be x cm then AB will be ( x − 4) cm

Ray BD divides ABC such that AD = 4 cm and CD = 6 cm

Triangles ABD and DBC are similar because

  ADB=BDC , since they are opposite to common arm

  

  ADB=BDC

  =ABC

AAA criteria of similarity is satisfied

Therefore, ratio of corresponding sides will be equivalent

Hence,

  ABBC=ADDCx4x=466(x4)=4x6x4x=242x=24x=12

And perimeter of triangle

  =x+x4+4+6=2x+6

At x = 12,

Perimeter = 2.12+6=30 units
