What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, a rule that states if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What does SAS stand for in triangle congruence?

Back

SAS stands for Side-Angle-Side, a rule that states 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 does ASA stand for in triangle congruence?

Back

ASA stands for Angle-Side-Angle, a rule that states if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What does AAS stand for in triangle congruence?

Back

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

Front

What does SSA indicate about triangle congruence?

Back

SSA (Side-Side-Angle) does not guarantee triangle congruence; two triangles can have two sides and a non-included angle equal but still not be congruent.

Front

What is the vertex form of a quadratic equation?

Back

The vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

Front

How do you find the vertex of a quadratic in vertex form?

Back

In the vertex form y = a(x - h)² + k, the vertex is the point (h, k).

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is y = ax² + bx + c.

Front

What is the formula to find the x-coordinate of the vertex of a quadratic in standard form?

Back

The x-coordinate of the vertex can be found using the formula x = -b/(2a).

Front

How do you solve for x in a linear equation?

Back

To solve for x in a linear equation, isolate x on one side of the equation using inverse operations.
