Topic 3&4 q.2

Front

What are parallel lines?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What does it mean for angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles on opposite sides of the transversal but inside the two lines. They are equal if the lines are parallel.

Front

What are alternate exterior angles?

Back

Alternate exterior angles are pairs of angles on opposite sides of the transversal but outside the two lines. They are equal if the lines are parallel.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

How can you prove that two angles are congruent?

Back

You can prove that two angles are congruent by showing that they are corresponding angles, alternate interior angles, or alternate exterior angles formed by a transversal with parallel lines.

Front

What is the significance of angle relationships in geometry?

Back

Angle relationships help in proving the properties of geometric figures and solving problems involving angles.

Front

What is the sum of the interior angles of a triangle?

Back

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