Question

lease Help- In ΔMNO shown below, segment NP is an altitude:


What property or definition is needed to prove that ΔMPN is similar to ΔNPO?

Question 7 options:

1) Transitive Property of Equality

2) Reflexive Property of Equality

3) Definition of an Altitude

4) Definition of Supplementary Angles

Answer 1

anyone?

Answer 2

do u want a pic of the triangle

Answer 3

sure ..

Answer 4

thts the whole question?

Answer 5

We know that N is right angle.

Answer 6

yes

Answer 7

so we need the definition of altitude: to show that P makes right angles.

Answer 8

how do i find that? (sorry im new to geometry)

Answer 9

What is definition of Altitude?

Answer 10

the height of an object or point in relation to sea level or ground level.

Answer 11

in geometry: The definition of the altitude of a triangle is a line that extends from one vertex of a triangle perpendicular to the opposite side.

Answer 12

oh ok

Answer 13

So definition of an Altitude: gives us NPM and NPO are 90 degrees .

that's enough to prove similarity.

Answer 14

If you assume \(m \angle M= x \) degrees:
\[m \angle O= 90-x \]

also, \(m \angle MNP= 90-x \)
and, \(m \angle ONP= x \)

Answer 15

so how does this answer my question

Answer 16

the answer is 3) Definition of an Altitude.

... since we needed to know that to prove the similarity above.
