Angle Types
An angle whose measure is less than 90 degrees.
What is an acute angle?
Lines that are always the same distance apart and never intersect.
What are parallel lines?
Opposite angles when two lines intersect.
What are vertical angles?
Degrees.
Intersecting streets, parking spaces, on ramps to freeways, bridges, driveways, etc
What are angle relationships in roads / streets / pavements, or a city?
An angle whose measure is 90 degrees.
What is a right angle?
A line that cuts across 2 or more lines.
What is a transversal?
Two non-overlapping angles that share a vertex and a side.
What are adjacent angles?
The sum of these three angles is 180 degrees.
What is the sum of the interior angles of a triangle?
Building stable structures, aesthetic design, roof slopes, load-bearing structures, complex shapes, stairwells, etc.
What are angle relationships in architecture or construction?
Angle whose measure is greater than 90 degrees.
What is an obtuse angle?
When two lines are cut by a transversal, a pair of angles on opposite sides of the transversal and between the two lines.
What are alternate interior angles?
Two angles that are adjacent and supplementary.
What is a linear pair?
The two angle relationships that are formed when two lines intersect?
What are vertical angles and linear pairs?
Determining trajectory, optimizing ball passes, controlling direction, launch angle, court positioning, field position, passing lanes, offensive angles, etc.
What are angle relationships in (playing) sports?
Two angles whose sum measures to 90 degrees.
What are complementary angles?
When two lines are cut by a transversal, a pair of angles in the same relative position.
What are corresponding angles?
Two angles that have exactly the same measurement?
What are congruent angles?
When parallel lines are cut by a transversal, the relationship of alternate interior angles, alternate exterior angles, and corresponding angles.
Used to determine direction, calculate distances, plot courses, mapping and positioning, celestial navigation, etc.
What are angle relationships in navitgation or mapping?
Two angles whose sum measures 180 degrees.
What are supplementary angles?
When two lines are cut by a transversal, a pair of angles on the same side of the transversal and between the two lines.
What are same-side interior angles? or What are consecutive interior angles?
When two lines are cut by a transversal, a pair of angles on opposite sides of the transversal and on the outside of the two lines.
What are alternate exterior angles?
When parallel lines are cut by a transversal, the relationship of same-side interior angles and same-side exterior angles.
What are supplementary angles?
Used to create perspective, imagery, proportion, balance, emotional impact, illusion of depth, feeling of movement, action, symmetry, balanced compositions, etc.
