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 the corresponding parts of another triangle.

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides (a² + b² = c²).

What is the difference between similar and congruent triangles?

Back

Similar triangles have the same shape but not necessarily the same size, while congruent triangles are identical in both shape and size.

What is the significance of the angle in the SAS congruence criterion?

Back

The angle in the SAS criterion is crucial because it is the included angle between the two sides being compared, ensuring that the triangles are congruent.

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

Back

Two triangles are congruent by SSS (Side-Side-Side) if all three sides of one triangle are equal to the three sides of the other triangle.

What is the method to solve for multiple variables in an equation?

Back

To solve for multiple variables, use substitution or elimination methods to reduce the number of variables and isolate each variable step by step.
