## jhonathanceballos 3 years ago http://oi46.tinypic.com/10fqdll.jpg What is JH? median perpendicular bisector angle bisector altitude

1. dpflan

So this is a multiple choice question. Do you have definitions for each term?

2. jhonathanceballos

Yes,But im not sure which one is the answer,i think is altitude but im i correct?

3. dpflan

Let's see. Why do you think altitude? What's it's definition?

4. dpflan

If you look at the diagram, there is a gray box next to point 'H' signifying a right angle, so the line segment 'JH' forms a right angle with line segment 'CB'

5. dpflan

A line segment representing 'altitude' must go through a vertex and form a right angle with one of the edges of the triangle.

6. dpflan

And, 'JH' can't be an 'altitude' because it originates at point J on line segment 'AB', not at a vertex.

7. jhonathanceballos

Oh alright,Well Im not sure which one is the answer,Do you have an idea>?

8. dpflan

I do, you're close if you chose altitude because of the formation of the 90 degree, right angle

9. dpflan

What other possibility requires the formation of a right angle?

10. jhonathanceballos

It has to be Perpendicular bisector then?

11. dpflan

Yeah man! And it's really the apt term because perpendicular basically means 'forms a right angle'

12. dpflan

You can also see the tick marks on either side of 'H' on the line segment 'CB'. Those marks signify that 'CH' and 'HB' have the same length, that's what the perpendicular bisector does: it basically splits the line segment into 2 separate and equal length parts

13. dpflan

So 'H' is the midpoint of 'CB' too

14. dpflan

Does this make sense?

15. jhonathanceballos

Yeah thanx @dpflan

No problem, good luck with the rest of your work
