Solution: Construct the vectors $\hat{ab}$, $\hat{ac}$ and take $\frac{1}{2} \hat{ab} \times \hat{ac} $. We take half of the resulting since the original gives the area of the parallelogram decsribed by the vectors. hype water bottleWeb【解析】 abc≅ def 理由如下因为ab⊥be，de⊥be所以∠b=∠e=90°.因为bf=ce，所以bc=fe.因为ab=de，∠b=∠e，bc=fe所以 abc≅ def .【全等三角形的基本性质】全等三角形的对应边相等，全等三角形的对应角相等【拓展】全等三角形对应边上的高线、中线和对应角的角平分线相等；全等三角形的周长、面积相等 ... hype waterproof shower radioWeb【题目】 已知 abc、 def 是两个完全一样的三角形，其中∠ acb=∠dfe=90°，∠a=∠d=30°. （1 ）将它们摆成如图①的位置（点 e、f 在 ab 上，点 c 在 df 上， de 与 ac 相交于点 g). 求∠ agd 的度数. （2 ）将图①的 abc 固定，把 def 绕点 f 按逆时针方向旋转 n°. hype wayne covid testing
