116a - Parallel Lines and Proportional Parts Flashcardizz

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet. They are always the same distance apart and have the same slope.

What is the Transversal Line?

Back

A transversal line is a line that intersects two or more lines at different points. It creates angles that can be analyzed for relationships.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines. They are equal when the lines are parallel.

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal. They are equal when the lines are parallel.

What is the Angle-Angle (AA) Similarity Postulate?

Back

The Angle-Angle (AA) Similarity Postulate states that if two angles of one triangle are equal to two angles of another triangle, the triangles are similar.

What is the concept of proportional parts?

Back

Proportional parts refer to segments or lengths that maintain a constant ratio to each other, often used in the context of similar triangles.

Front

How do you find the length of a segment in similar triangles?

Back

To find the length of a segment in similar triangles, set up a proportion using the lengths of corresponding sides and solve for the unknown length.

What is the Basic Proportionality Theorem (or Thales' theorem)?

Back

The Basic Proportionality Theorem states that if a line is drawn parallel to one side of a triangle, it divides the other two sides proportionally.

Front

What is the relationship between the slopes of parallel lines?

Back

The slopes of parallel lines are equal. If two lines have the same slope, they will never intersect.
