Parallel lines cut by a transversal

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.

Front

What is a transversal?

Back

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

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.

Front

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.

Front

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.

Front

What are same-side interior angles?

Back

Same-side interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

Front

What are same-side exterior angles?

Back

Same-side exterior angles are pairs of angles that lie outside two lines and on the same side of a transversal.

How do you find the value of x in the equation 12X - 29 + 4X + 1 = 180?

Back

Combine like terms: 16X - 28 = 180. Then, add 28 to both sides: 16X = 208. Finally, divide by 16: X = 13.

Front

How do you solve the equation 8X - 17 = 5X + 19?

Back

Subtract 5X from both sides: 3X - 17 = 19. Then, add 17 to both sides: 3X = 36. Finally, divide by 3: X = 12.

What is the sum of the interior angles formed by a transversal intersecting two parallel lines?

Back

The sum of the interior angles formed by a transversal intersecting two parallel lines is 180 degrees.
