What is the SSS triangle congruence criterion?

Back

The SSS (Side-Side-Side) criterion states that if three sides of one triangle are equal to three sides of another triangle, then the two triangles are congruent.

Front

What type of triangle has all sides of different lengths?

Back

A scalene triangle.

Front

What is the definition of a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

Front

What does the term 'congruent triangles' mean?

Back

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

Front

Which triangle congruence criteria is invalid?

Back

AAA (Angle-Angle-Angle) is not a valid triangle congruence criterion.

Front

If two triangles have two sides equal and the included angle equal, what is the congruence criterion?

Back

The SAS (Side-Angle-Side) criterion.

Front

What is the relationship between corresponding sides of congruent triangles?

Back

Corresponding sides of congruent triangles are equal in length.

Front

If ∆ABC ≅ ∆DEF, what can we say about angle A and angle D?

Back

Angle A is equal to angle D.

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length.

Front

What does SSA stand for in triangle congruence?

Back

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