WebHeron works of course but it would be simpler to take half the length of the cross product $(b-a)\times(c-a)$. 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. portsmouth crisis team numberWeb【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°. opulice helmet destiny 2opulnow on bingWebf e b c （2）如果具备：ab=de，bc=ef，ac=df； ∠a=∠d，∠b=∠e，∠c=∠f。 那么可以得出 abc ≌ def 。 例 如图 abc沿着bc的方向平移至 def ， ∠a =800， ∠b =600，求∠f的度数。 ad 解：由图形平移的特征，可知 abc 与 def的形状与大小相同，即 应相等，那么这两个三角形 ... opulus healthhttp://www.1010jiajiao.com/czsx/shiti_id_d0f9ee4d295a193e6e03bf82cc7d6f16 portsmouth cricket club play cricketWebSep 6, 2024 · In ∆ ABC and ∆DEF ∠ B = ∠ E, ∠ F = ∠ C and AB = 3DE then which of the statements regarding the two triangles is true ?
