Answer:
The statement If ∠A ≅ ∠C not prove that Δ ABD ≅ Δ CBD by SAS ⇒ C
Step-by-step explanation:
* Lets revise the cases of congruence
- SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and
including angle in the 2nd Δ
- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ
≅ 2 angles and the side whose joining them in the 2nd Δ
- AAS ⇒ 2 angles and one side in the first triangle ≅ 2 angles
and one side in the 2ndΔ
- HL ⇒ hypotenuse leg of the first right angle triangle ≅ hypotenuse
leg of the 2nd right angle Δ
* Lets solve the problem
- In the 2 triangles ABD , CBD
∵ AB = CB
∵ BD is a common side in the two triangles
- If AD = CD
∴ Δ ABD ≅ Δ CBD ⇒ SSS
- If BD bisects ∠ABC
∴ m∠ABD = m∠CBD
∴ Δ ABD ≅ Δ CBD ⇒ SAS
- If ∠A = ∠C
∴ Δ ABD not congruent to Δ CBD by SAS because ∠A and ∠C
not included between the congruent sides
* The statement If ∠A ≅ ∠C not prove that Δ ABD ≅ Δ CBD by SAS
Vertex of parabola is y=
at (4,6)
Step-by-step explanation:
The given equation of parabola is y= 
Simplifying the equation,
y= 
y= 
y= 
y= ![(-1)[(x^{2} -8x + 16)-(16-22)]](https://tex.z-dn.net/?f=%28-1%29%5B%28x%5E%7B2%7D%20-8x%20%2B%2016%29-%2816-22%29%5D)
y= ![(-1)[(x-4)^{2}+(+6)]](https://tex.z-dn.net/?f=%28-1%29%5B%28x-4%29%5E%7B2%7D%2B%28%2B6%29%5D)
y= 
y= 
The general equation of parabola is y = y= 
Where, (h,k) is vertex of parabola.
On comparing the equations
we get,
Vertex of parabola is y=
at (4,-6)
