Exploring Parallel Lines and Transversals

Miss Curly teaches about parallel lines cut by a transversal, covering types of angles such as interior, exterior, alternate, corresponding, and vertical angles. She explains how these angles relate to each other and provides problem-solving examples to find missing angles and solve for variables. The lesson emphasizes understanding angle relationships and using them to solve geometry problems.

What are parallel lines?

• Lines that intersect at a right angle

• Lines that cross each other at any angle

• Lines that never intersect

• Lines that are perpendicular to each other

What are alternate interior angles?

• Angles on opposite sides of the transversal and inside the parallel lines

• Angles on the same side of the transversal and outside the parallel lines

• Angles that add up to 180 degrees

• Angles that are adjacent to each other

What are corresponding angles?

• Angles that are supplementary
