What does SSA stand for in triangle congruence?

Back

SSA stands for Side-Side-Angle, which is not a valid criterion for proving triangle congruence.

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, which is a valid criterion for proving triangle congruence.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, which is a valid criterion for proving triangle congruence.

What does AAA stand for in triangle congruence?

Back

AAA stands for Angle-Angle-Angle, which is not a valid criterion for proving triangle congruence.

Front

If two triangles have two angles and the included side equal, what can be concluded?

Back

The triangles are congruent by the ASA (Angle-Side-Angle) criterion.

Front

If two triangles have three sides equal, what can be concluded?

Back

The triangles are congruent by the SSS (Side-Side-Side) criterion.

Front

If two triangles have two sides and the angle between them equal, what can be concluded?

Back

The triangles are congruent by the SAS (Side-Angle-Side) criterion.

Front

If two triangles have two angles equal, what can be concluded?

Back

The triangles are similar, but not necessarily congruent unless the sides are also proportional.

Front

What is the significance of congruent triangles in geometry?

Back

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