Parallel Lines & Transversals Geo Ch 3 Half

Front

What is the relationship between Angle 3 & 7 when they are formed by parallel lines and a transversal?

Back

Corresponding angles are formed when a transversal intersects two parallel lines, creating pairs of angles that are in the same position relative to the parallel lines.

Front

What is the sum of the interior angles of an octagon?

Back

The sum of the interior angles of an octagon is 1080°.

Front

If x + 2 = 10, solve for x.

Back

x = 8.

Front

What is the construction called when you draw a line parallel to a given line through a point not on the line?

Back

Parallel line to a point not on the line.

Front

In the context of geometry, 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, no matter how far they are extended.

Front

What are alternate interior angles?

Back

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

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

How do you calculate the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon can be calculated using the formula (n-2) × 180°, where n is the number of sides.

Front

What is the definition of a transversal in geometry?

Back

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

Front

What are vertical angles?

Back

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