Answer:

∠ACB ≅ ∠ACD

Step-by-step explanation:

The SAS Postulate tells us:

If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

(Congruent = exactly the same)

(included angle is formed by the two known sides)

In this example we can see that 2 sides are congruent (by the dashes on the lines and the fact that both triangles share side AC), but we do not know if the included angles are congruent.

Therefore, we need to know if ∠ACB ≅ ∠ACD

Which is the general form of the equation of the circle shown? x2 + y2 + 4x – 2y – 4 = 0 x2 + y2 + 4x – 2y + 2 = 0 x2 + y² – 4x

Lunna [17]

The equation of a circle with center at point (h, k) and radius of r units is given by
$(x-h)^{2} +(y-k)^2=r^2$

From the diagram, the center of the given circle is at points (-2, 1) and the radius is 3 units.

Therefore, the equation of the given by
$\left(x-(-2)\right)^2+(y-1)^2=3^2 \\ \\ (x+2)^2+(y-1)^2=9 \\ \\ x^2+4x+4+y^2-2y+1=9 \\ \\ x^2+y^2+4x-2y+5-9=0 \\ \\ x^2+y^2+4x-2y-4=0$
