Step-by-step explanation:

Step 1:  Answer question 1

What we are doing in this problem, is that we are squaring both sides in order to help simplify.  Number 1 has the second option or B.

Step 2:  Answer question 2

What we are doing is that we are finding the distance from the point on the parabola to the directrix.  Number 2 has the last option or F.

Step 3:  Answer question 3

Use (x, y)

What we are doing is that we are finding a point on a parabola.  Number 3 has the fifth option or E.

Step 4:  Answer question 4

What we are doing is that we are writing the equation of the parabola.  Number 4 has the third option or C.

Step 5:  Answer question 5

What we are doing is that we are setting the distance from focus to the point equal to the distance from directrix.  Number 5 has the first option or A.

Step 6:  Answer question 6

What we are doing is that we are finding the distance from the point on the parabola to the directrix .  Number 5 has the fourth option or D.

answer: it is d

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
