A line <u>bisector</u> is a <em>straight </em>line that <u>divides</u> a given line into two equal parts. Thus the following steps are required by Naomi to show that point D is <em>equidistant</em> from points  A and C.

BD ⊥ AC (given)

BD = 3 units, and AC = 8 units.

BD is the <em>perpendicular</em> bisector of <u>segment</u> AC (given)

Thus,

<BDA  ≅ <BDC <em>(right</em> angles formed by a <u>perpendicular</u> bisector)

AD ≅ DC <em>(equal</em> parts of a<em> bisected l</em>ine)

AD ≅ DC = 4 units

Thus joining <u>points</u> B to A, and B to C,

BA ≅ BC.

So that applying <em>Pythagoras</em> theorem to ΔABD, we have:

/hyp/^{2} = Adj 1^{2} + Adj 2^{2}

AB^{2} = 3^{2} + 4^{2}

       = \sqrt{25}

 AB      = 5 units

So that,

BA ≅ BC = 5 units

Therefore, it can be <u>concluded</u> that point D is <em>equidistant</em> from points A and C.

What is the length of segment AC?
Andrei [34K]

Answer:

10 units

Step-by-step explanation:

To find the length we can use the formula

d = sqrt( (y2-y1)^2 + (x2-x1)^2)

We have the two points (-5,5) and (3,-1)

d = sqrt( (-1-5)^2 + (3--5)^2)

d = sqrt( (-6)^2 + (3+5)^2)

d = sqrt( (-6)^2 + (8)^2)

d = sqrt( 36 + 64)

d = sqrt(100)

d = 10
