SSS SAS Congruence

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, which is a theorem stating that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, which is a theorem stating that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the two triangles are congruent.

Front

What is the SSS Congruence Postulate?

Back

The SSS Congruence Postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the SAS Congruence Postulate?

Back

The SAS Congruence Postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What additional information is needed to use the SAS theorem?

Back

To use the SAS theorem, you need to know the lengths of two sides and the measure of the included angle between those sides.

Front

Can SSS be used if only two sides are known?

Back

No, the SSS theorem requires all three sides of the triangles to be known to prove congruence.

Front

What is the significance of congruent triangles in geometry?

Back

Congruent triangles have the same size and shape, which means their corresponding sides and angles are equal.

Front

How can you prove triangles are congruent using SSS?

Back

To prove triangles are congruent using SSS, measure the lengths of all three sides of both triangles and show that they are equal.

Front

How can you prove triangles are congruent using SAS?

Back

To prove triangles are congruent using SAS, measure two sides and the included angle of both triangles and show that they are equal.

Front

What is the relationship between congruence and similarity in triangles?

Back

Congruent triangles are similar, but similar triangles are not necessarily congruent. Congruent triangles have equal corresponding sides and angles, while similar triangles have proportional sides and equal corresponding angles.
