Classifying Lines and Angles: Part 1 Insights

What does it mean to classify two-dimensional figures?

• To sort them based on color and texture

• To arrange them based on size and shape

• To group them based on line and angle properties

• To label them based on their molecular structure

What are parallel lines?

• Lines that intersect at any angle

• Lines that never meet, regardless of length

• Lines that intersect at a right angle

• Lines that curve and meet

What type of angle is formed by perpendicular lines?

• Obtuse angle

• Right angle

• Acute angle

• Straight angle

What is the angle range of an obtuse angle?

• More than 90 degrees but less than 180 degrees

• Less than 90 degrees

• 180 degrees

• Exactly 90 degrees

What does the presence of a right angle indicate about the lines?

• The lines are perpendicular

• The lines are parallel

• The lines are intersecting at an obtuse angle

• The lines are neither parallel nor perpendicular

What defines a trapezoid?

• A quadrilateral with one set of parallel lines

• A quadrilateral with no parallel sides

• A quadrilateral with all sides of equal length

• A quadrilateral with two sets of parallel lines

How many sets of parallel lines does a parallelogram have?

• None

• Three

• One

• Two

Which shape is not necessarily a parallelogram?

• Rhombus

• Square

• Trapezoid

• Rectangle

What is unique about the sides of a rhombus?

• No sides are parallel

• All sides are of the same length

• Only two sides are of equal length

• All sides are of different lengths

Which statement is true about a square in terms of its sides?

• All sides are parallel

• All sides are of the same length

• All sides are of different lengths

• No sides are parallel
