D is correct

OpenStudy (anonymous):

Can you explain?

OpenStudy (pawanyadav):

Orthocentre is the point intersection of altitude to all side from opposite vertices

OpenStudy (math&ing001):

The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side.

OpenStudy (math&ing001):

Can you guess which one is correct ?

OpenStudy (anonymous):

Is it D?

OpenStudy (math&ing001):

Nope, perpendicular bisector looks like this: |dw:1448305449225:dw|

OpenStudy (anonymous):

C?

OpenStudy (math&ing001):

|dw:1448305587426:dw| You can see that it doesn't necessarily passes through a vertex of the triangle ABC.

OpenStudy (anonymous):

Is it C?

OpenStudy (math&ing001):

Nope, did you get what a triangle altitude is ?

OpenStudy (anonymous):

not really. :(

OpenStudy (math&ing001):

Ok here's an example. I want you to draw the altitude that passes through the vertex A. I'll help you through it |dw:1448305886597:dw|

OpenStudy (anonymous):

|dw:1448305935452:dw|

OpenStudy (anonymous):

?

OpenStudy (math&ing001):

|dw:1448305978499:dw| AE must be perpendicular to BC.

OpenStudy (math&ing001):

|dw:1448306082937:dw| Here try again :)

OpenStudy (anonymous):

Would that make it B?

OpenStudy (math&ing001):

Yep !

OpenStudy (anonymous):

Awesome. Thanks so much!
