@phi !?

@robtobey

OpenStudy (anonymous):

Can you help me @triciaal??

OpenStudy (anonymous):

Triangle ZBY = Triangle ORW

OpenStudy (anonymous):

what is SSS AND SAS?

OpenStudy (triciaal):

do you mean like ZB = OR BY = RW ZY= OW SSS = side side side SAS = side angle side

OpenStudy (anonymous):

You don't need sss and sas for congruence statements. you just need to relate the sides of the triangles to show they are congruent to each other.

OpenStudy (anonymous):

The answers available on the worksheet. Are written like ZYB = OWR by SAS, ZYB = WOR by SSS, ect.

OpenStudy (anonymous):

The letters are in different orders with either SSS or SAS written next to them.

OpenStudy (anonymous):

Oh, simple trig then. using the sides find the angles I guess, then compare angles from one triangle to the angles of the other.

OpenStudy (triciaal):

look at each triangle and match them up exactly to name the sides correctly

OpenStudy (triciaal):

" if three sides of one triangle are congruent to three sides of a second triangle , then the two triangles are congruent."

OpenStudy (triciaal):

that is the side-side-side (sss) congruence Postulate

OpenStudy (anonymous):

So this one would SSS?

OpenStudy (triciaal):

Postulate 20 if two sides and the included angle of one triangle are congruent to the two sides and the included angle of a second triangle, then the two triangles are congruent

OpenStudy (triciaal):

I think this would be SSS because that's what you were given ( the units to compare) name correctly is important here

OpenStudy (anonymous):

How do I know what order the letters should come in? @triciaal

OpenStudy (triciaal):

start with any one and find the corresponding measurement on the second example when I named the sides above ZB = OR not ZB = OW or ZB = RW
