What is the SAS postulate in triangle congruence?

Back

The SAS (Side-Angle-Side) 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 two triangles are congruent.

Front

What are remote interior angles in relation to an exterior angle?

Back

Remote interior angles are the two angles inside a triangle that are not adjacent to a given exterior angle.

Front

How do you find the value of x in a geometric problem?

Back

To find the value of x, set up an equation based on the properties of the shapes involved, such as angles or side lengths, and solve for x.

Front

What is a midsegment in a triangle?

Back

A midsegment is a line segment that connects the midpoints of two sides of a triangle and is parallel to the third side.

Front

How do you solve for angles in a triangle?

Back

To solve for angles in a triangle, use the triangle sum theorem which states that the sum of the interior angles of a triangle is always 180 degrees.

Front

What does the SSS postulate state?

Back

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

Front

What is the ASA postulate in triangle congruence?

Back

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the two triangles are congruent.

Front

What is the AAS postulate in triangle congruence?

Back

The AAS (Angle-Angle-Side) postulate states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Front

What is the relationship between angles in a linear pair?

Back

Angles in a linear pair are supplementary, meaning their measures add up to 180 degrees.

Front

How do you calculate the length of a midsegment?

Back

The length of a midsegment is half the length of the third side of the triangle.
