Front

What is a congruence statement?

Back

A congruence statement indicates that two geometric figures are congruent, meaning they have the same shape and size. For example, ΔLEU≅ΔELG means triangle LEU is congruent to triangle ELG.

Front

What does it mean for angles to be supplementary?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How do you write the equation of a vertical line?

Back

The equation of a vertical line is written in the form x = a, where 'a' is the x-coordinate of any point on the line.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of two perpendicular lines are negative reciprocals of each other, meaning their product is -1.

Front

How do you find the value of x in an equation?

Back

To find the value of x, isolate x on one side of the equation using algebraic operations.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the formula for the slope of a line?

Back

The slope (m) of a line through two points (x1, y1) and (x2, y2) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if their corresponding sides and angles are equal.

Front

What is the significance of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

How do you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.
