Can you prove these triangles are congruent using the SAS Theorem?
Yes. RT = UT
ST = VT
and <T = <T.
Yes. RT = TU
ST = UT
and <U = <S.
No. SR is not equal to UV.
No. There is not enough information.
Can you prove these are congruent using SAS Theorem?
Yes. There are 2 sides and an included angle congruent.
Yes. There are 2 angles and 1 side congruent.
No. The angle is not an included angle.
No. ML is not equal to QP.
No. There is not enough information,
Congruent figures...
Have the same dimensions (side lengths and angle measures)
Are the same shape and size
Can be mapped onto one another using rigid motions
All of the above
Are the following triangles congruent? If so, how do you know?
Yes. because of there are 2 sides and an included angle that are congruent.
Yes. because there are 2 angles and one side congruent.
No because the angle is not an included angle.
No because YZ does not equal ZW.
No, not enough information given
