SAS and SSS

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a criterion for triangle congruence where two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a criterion for triangle congruence where all three sides of one triangle are equal to the three sides of another triangle.

Front

What is a right triangle?

Back

A right triangle is a triangle in which one angle measures exactly 90 degrees.

Front

How can you determine if two triangles are congruent using SAS?

Back

Two triangles are congruent by SAS if two sides of one triangle and the angle between them are equal to two sides of another triangle and the angle between them.

Front

How can you determine if two triangles are congruent using SSS?

Back

Two triangles are congruent by SSS if all three sides of one triangle are equal to all three sides of another triangle.

Front

What is the significance of corresponding sides in triangle congruence?

Back

Corresponding sides are the sides of two triangles that are in the same relative position. For triangles to be congruent, their corresponding sides must be equal.

Front

What is the congruence statement for triangles?

Back

A congruence statement is a way to express that two triangles are congruent, indicating the corresponding vertices and sides, such as ΔABC ≅ ΔPRC.

Front

What is an acute triangle?

Back

An acute triangle is a triangle where all three angles are less than 90 degrees.

Front

What is an obtuse triangle?

Back

An obtuse triangle is a triangle that has one angle greater than 90 degrees.

Front

If two triangles are not congruent, what can be said about their corresponding sides and angles?

Back

If two triangles are not congruent, at least one pair of corresponding sides or angles is not equal.
