Midpoints, Angles, and Congruence

Front

What is the definition of a midpoint on a number line?

Back

A midpoint is the point that divides a line segment into two equal parts.

Front

How do you calculate the distance between two points A and D on a number line?

Back

Distance = |D - A|.

Front

What is the formula to find a point B that is a fraction of the distance from A to D?

Back

B = A + k * (D - A), where k is the fraction.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if their measures add up to 180 degrees.

Front

What is a linear pair of angles?

Back

A linear pair of angles are two adjacent angles that form a straight line.

Front

What are undefined terms in Euclidean geometry?

Back

Undefined terms are basic concepts that are not formally defined but are understood intuitively, such as point, line, and plane.

Front

What is a conjecture in geometry?

Back

A conjecture is a statement that is believed to be true based on observations but has not been proven.

Front

What is a rhombus?

Back

A rhombus is a quadrilateral with all four sides of equal length, but it does not necessarily have right angles.

Front

What is the difference between a rectangle and a square?

Back

A rectangle has opposite sides equal and all angles are right angles, while a square has all sides equal and all angles are right angles.

Front

How do you determine if two angles are congruent?

Back

Two angles are congruent if they have the same measure.
