(1)理论讲解（TheoreticalExplanation）

a.使用定语从句引入PythagoreanTheorem的定义：“AccordingtoPythagoreanTheorem,thesquareofthehypotenuseinarighttriangleisequaltothesumofthesquaresoftheothertwosides.”

b.使用状语从句阐述Theorem的应用范围：“Thistheoremcanbeappliedtosolveavarietyofreallifeproblems.”

c.使用宾语从句引导学生的思考：“WhatothermathematicalconceptscanyoubinewiththePythagoreanTheorem?”

(2)实践应用（PracticalApplication）

a.
