What is JH?


median

perpendicular bisector

angle bisector

altitude

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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'

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

What other possibility requires the formation of a right angle?

Answer 10

It has to be Perpendicular bisector then?

Answer 11

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

Answer 12

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

Answer 13

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

Answer 14

Does this make sense?

Answer 15

Yeah thanx @dpflan

Answer 16

No problem, good luck with the rest of your work
