Since it is given that AB ≅ AC, it must also be true that AB = AC. Assume ∠B and ∠C are not congruent. Then the measure of one a
kherson [118]

Answer:

\angle B\cong \angle C

Step-by-step explanation:

We are given that

AB\cong AC

We have to prove that \angle B\cong \angle C

AB\cong AC

Therefore, AB=AC

Suppose , angle B and angle C are not congruent.

Then, the measure of one angle is greater than the other.

If m\angle B > \angle C

Then , AC > AB

By using triangle parts theorem

It states that when an angle is greater than other then opposite side of greater angle is greater than the opposite side of other angle.

If m\angle B < m\angle C

Then, AC < AB.

It is contradiction because we are given AB=AC.

Therefore, it can be concluded that

\angle B\cong \angle C

To find the x coordinate of the vertex

x = -b/2a  where ax^2 +bx +c

a=1 b=0 c=0

x = -0/2(1) = 0

The y value is found by substituting into the equation

y = (0)^2 =0

The vertex is (0,0)
