HW: Cumulative Review

Front

What is translation in geometry?

Back

Translation is a geometric transformation that moves every point of a shape a constant distance in a specified direction.

Front

How do you describe a translation using coordinates?

Back

A translation can be described using a vector, indicating how far to move in the x (horizontal) and y (vertical) directions.

Front

What is the sum of angles in a triangle?

Back

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

Front

What is the relationship between parallel lines and angles?

Back

When two parallel lines are cut by a transversal, the corresponding angles are equal, and the alternate interior angles are equal.

Front

How do you calculate the measure of an angle in a triangle?

Back

To find the measure of an angle in a triangle, subtract the sum of the other two angles from 180°.

Front

What is the definition of a linear equation?

Back

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they are in the same plane and do not intersect, meaning they have the same slope.

Front

What is the definition of an angle?

Back

An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex).

Front

How do you find the measure of an angle formed by intersecting lines?

Back

The measure of an angle formed by intersecting lines can be found using the properties of vertical angles, which are equal, and adjacent angles, which are supplementary.
