TRIANGLE HELP

OpenStudy (mathstudent55):

Which parts of one triangle are congruent to corresponding parts of the other triangle?

OpenStudy (jdoe0001):

anything wrong with posting .gif or jpeg files?

OpenStudy (anonymous):

I don't know how to post those @jdoe0001

OpenStudy (jdoe0001):

just take a screenshot of the material, and paste it in PAINT or some graphic app, save and [Attach File] here

OpenStudy (jdoe0001):

is quicker and concise, then reading 10 pages in a .doc

OpenStudy (anonymous):

@jdoe0001

OpenStudy (jdoe0001):

yeap

OpenStudy (mathstudent55):

Now that the technical aspect is over, are you still interested in working this out?

OpenStudy (anonymous):

The triangles are congruent because they are acute angles right @mathstudent55

OpenStudy (jdoe0001):

I can see 2 pair of sides equal there, the diagonal is being shared by both, thus equal to both

OpenStudy (mathstudent55):

No. There are specific ways of proving two triangles congruent. They are asking which one can be used in this case.

OpenStudy (anonymous):

congruent means the same right ? @mathstudent55

OpenStudy (mathstudent55):

congruent means same size

OpenStudy (anonymous):

in the picture looks like they are both the same size . but in this case we are trying to prove which one to use correctly @mathstudent55

OpenStudy (mathstudent55):

Yes. Which of those methods can you use to prove the two triangles congruent? The choices are: A. Not congruent B. SSA = side - side - angle C. HL = hypotenuse - leg D. ASA = angle - side - angle

OpenStudy (anonymous):

i think it would be D @mathstudent55

OpenStudy (mathstudent55):

For ASA, you need to show that an angle, a side and an angle of 1 triangle are congruent to the same parts of the other triangle. I see a side and an angle, but I don't see another angle being congruent.

OpenStudy (anonymous):

SSA, because we want to see if they are congruent so we chech the sides and the two angles that are there @mathstudent55

OpenStudy (mathstudent55):

The problem is that SSA is not a method. It's a choice only to trick you. The only two choices that are real methods of proving triangles congruent are ASA and HL. It's not ASA.
