<p>so i started working on the New BB 2nd Ed. and in the 1st practice test (section 8) i didn't get problem # 2. its on page 419. it seems really easy but i don't get why its answer choice E instead of choice D.</p>

<p>In the figure above point A is the center of the circle and segments BD and CE are diameters. Which of the following statements is true?</p>

<p>A) CA>6
B) ED>4
C) BA<4
D) CA=4
E) ED=4</p>

<p>Type up the problem and I’ll give you a solution.</p>

3

<p>Whoops! Wrong thread</p>

4

<p>bump. i added the problem btw.</p>

5

<p>Clarification: is BC = 4 and AD = 6?</p>

<p>I’ll go through the answer choices</p>

<p>A - No, CA = 6 because it’s a radius of the circle and AD (also a radius) = 6
B - No, ED = 4. ABC and AED are congruent triangles because of SAS (each has two sides that are radii, and the two triangles have a congruent angle). BC = 4 so the corresponding side of the other triangle (ED) is also 4.
C - No, BA = 6. It is a radius of the circle.
D - No, CA = 6. It is a radius of the circle.
E - Yes (see explanation for choice B)</p>

<p>^ yes i get it now. i just visually interpreted the question wrong. thanks!</p>
