Semester 1 Final Review

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 it mean if segment KD is parallel to segment JP?

Back

It means that the two segments will never intersect and are equidistant from each other at all points.

Front

How do you solve for x in an equation?

Back

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

Front

What is the sum of angles in a triangle?

Back

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

Front

How do you find the midpoint between two points?

Back

The midpoint is found by averaging the x-coordinates and the y-coordinates of the two points. For points (x1, y1) and (x2, y2), the midpoint is ((x1+x2)/2, (y1+y2)/2).

Front

What is the AAS criterion for triangle congruence?

Back

AAS stands for Angle-Angle-Side, a criterion for triangle congruence where two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle.

Front

What does it mean if two segments are congruent?

Back

It means that the two segments have the same length.

Front

What is the definition of a perpendicular line?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

How do you calculate the angle of a triangle if two angles are known?

Back

Subtract the sum of the known angles from 180 degrees to find the third angle.

Front

What is the SSS criterion for 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.
