What does SSS stand for in triangle congruence?

Back

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

Front

What is the SSS Congruence Postulate?

Back

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

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 is the ASA Congruence Postulate?

Back

If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the AAA criterion?

Back

AAA stands for Angle Angle Angle; it indicates that if three angles of one triangle are equal to three angles of another triangle, the triangles are similar but not necessarily congruent.

Front

What is the definition of congruent triangles?

Back

Congruent triangles are triangles that are identical in shape and size, meaning all corresponding sides and angles are equal.

Front

What is the relationship between interior angles of a polygon?

Back

The sum of the interior angles of a polygon with n sides is (n-2) × 180°.

Front

What is the relationship between exterior angles of a polygon?

Back

The sum of the exterior angles of any polygon is always 360°, regardless of the number of sides.

Front

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

Back

The triangles are similar by the AA (Angle Angle) similarity criterion.

Front

What is the definition of a rate in mathematics?

Back

A rate is a ratio that compares two quantities with different units, often expressed as a fraction.
