Parallel line
What is a parallel line?
A Parallel line is 2 or more lines where they never intersect
What is a transversal line?
a line that cuts across two or more lines in the same plane.
What is a interior angle?
The angles that lie inside a shape.
What is a exterior angle?
Its measure is equal to the sum of the two non-adjacent interior angle measures,
What is a corresponding angle?
Corresponding angles occur when a transversal line crosses two parallel lines.
Do Parallel lines eventually intersect?
No, they never intersect, no matter how far you try to extend them in any given direction.
Are transversal lines straight?
Yes, transversals are straight lines that intersect two or more lines at different points
What angle does an interior angle add up to?
180 degrees
What is the difference between interior and exterior angles?
Any angle that is on the inside of a shape is called an interior angle. Any angle that is on the outside of a shape is called an exterior angle.
What do corresponding angles add up to?
180 degrees
Why do parallel lines never intersect
the distance between them will never be zero.
How many degrees is a transversal line?
180 degrees
What shape has all interior angles?
A polygon
What shape has all exterior angles?
A polygon
When are corresponding lines equal?
if a transversal intersects two parallel lines, the corresponding angles will be always equal.
Parallel lines intersect at any point
False
What is the purpose of a transversal line
Transversals play a role in establishing whether two or more other lines in the Euclidean plane are parallel.
What does a exterior angle add up to?
360 degrees
How do you identify corresponding sides?
Corresponding sides are the sides that are in the same position in any different 2-dimensional shapes.
How many solutions does a parallel line have?
Zero Solutions
Properties of a transversal angle
Vertically opposite angles are equal.
What is the formula of an interior angle?
( n − 2 ) × 180 ∘
What is the formula of an exterior angle?
An exterior angle of a polygon = 360°/ Number of sides of the polygon.
Are corresponding angles supplementary or congruent?
Corresponding angle are congruent
