Front

What is the measure of angle S if it is given that ∠S = 60 degrees?

Back

∠S = 60 degrees.

Front

If YW is the perpendicular bisector of XZ, can triangle YWX be congruent to triangle YWZ?

Back

Yes, by the SAS (Side-Angle-Side) postulate.

Front

Define a perpendicular bisector.

Back

A line that divides a segment into two equal parts at a 90-degree angle.

Front

What does the SAS postulate state?

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 definition of a vertex in geometry?

Back

A vertex is a point where two or more lines meet, forming an angle.

Front

Explain the concept of congruent triangles.

Back

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

Front

What is the significance of the angle measure in a triangle?

Back

The sum of the interior angles in a triangle always equals 180 degrees.
