Finding Triangle Congruence with Little Information

# data[].attributes.body
We were given triangles with congruent side marks but no numbers. We had to find triangles with little information and prove that they were congruent.

# data[].attributes.body
If two sides of a triangle are congruent, then the angles opposite them are congruent.

# data[].attributes.body
You have to find the angle inside the triangle then you can find the angles outside the triangle , then you can check your answer by Seeing if they add up to 180

# data[].attributes.body
if two sides and the included angle of one triangle, then the two triangles are congruent.

# data[].attributes.body
if two angles of one triangle are congruent to two angles of another triangle, then the third angles are also congruent.
