feet. This valueis approximatelyequalto feet.


LessonSummary


In this lesson,we exploredhow to workwith differentradicalsboth in theoryand in practicalsituations.
Specifically, we havelearned:



  • How to identifyand use the ratiosinvolvedwith right isoscelestriangles.

  • How to identifyand use the ratiosinvolvedwith triangles.

  • How to identifyand use ratiosinvolvedwith equilateraltriangles.

  • How to employright triangleratioswhensolvingreal-worldproblems.


Theseskillswill help you solvemanydifferenttypesof problems.Alwaysbe on the lookoutfor new and in-
terestingwaysto find relationshipsbetweensidesand anglesin triangles.
