SSS and SAS

Front

What does SSS stand for?

Back

Side Side Side

Front

Which triangle congruence theorem can be used to prove triangles are congruent if all three sides of one triangle are equal to the three sides of another triangle?

Back

SSS (Side Side Side) congruence theorem.

Front

What is the included side in triangle DEF between angles D and E?

Back

Side DE.

Front

Which triangle congruence theorem can be used to prove triangles are congruent if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle?

Back

SAS (Side Angle Side) congruence theorem.

Front

If two triangles have three pairs of equal sides, what can be concluded about the triangles?

Back

The triangles are congruent by the SSS theorem.

Front

What is the difference between SSS and SAS in triangle congruence?

Back

SSS requires all three sides to be equal, while SAS requires two sides and the included angle to be equal.

Front

Can SSS be used to prove congruence if only two sides are known?

Back

No, SSS requires all three sides to be known.

Front

What is the significance of the included angle in the SAS theorem?

Back

The included angle is the angle formed between the two sides being compared.

Front

If triangle ABC has sides of lengths 5, 7, and 10, and triangle DEF has sides of lengths 5, 7, and 10, what can be concluded?

Back

Triangles ABC and DEF are congruent by SSS.

Front

What is the formula to determine if two triangles are congruent using SSS?

Back

Compare the lengths of all three sides of both triangles.
