Here's Some Leftovers!!
Study Buddy
100
A portion of a line delimited by two end points. (Also: a line described by 2 sets of coordinates and the shortest path between them)
What is a line segment?
100
The figure formed by 2 lines that start at the same time. *Measured in degrees*
What is an angle
100
A quadrilateral with four equal sides is called THIS.
What is a SQUARE
100
When 2 lines are crossed by another line. The pairs of angles on opposite lines of the transversal but outside the 2 lines are called THIS...
What Are ALTERNATE EXTERIOR ANGLES
100
~To Help You Remember~ The angle pairs are on "Alternate" sides of the Transversal (aka line), and they are on the "Interior" of 2 crossed lines.
Use this fact and you'll do fine! Don't press + or - ! that's cheating; there was NO QUESTION!
200
Lines that are at right angles (90 degrees) to each other.
What are perpendicular lines?
200
If 2 angles add up to 90 degrees (a right angle)
What are COMPLIMENTARY ANGLES
200
A quadrilateral with 2 sets of equal sides is called THIS...
What is a RECTANGLE
200
A POLYGON with at least 2 opposite edges that are parallel.
What is a TRAPEZOID
200
*To Help You Remember* The angle pairs are on "alternate" sides of the transversal (aka line), and they are on the "exterior" of the 2 crossed lines.
Use this factoid and you'll do just fine! Good luck! Don't you forget!!! Don't click + or -. There's no question!
300
Lines that have on and ONLY one point in common (THINK: the OPPOSITE of Parallel)
What are intersecting lines
300
2 angles are THIS if they add up to 180 degrees (a straight line)
What are SUPPLEMENTARY ANGLES
300
A flat shape with opposite sides that are parallel and equal in length.
What is a PARALLELOGRAM
300
None
Don't press + or -, there's no question!
300
To measure an angle, use this awesome thing called a..
What is a protractor? They work really well!!!
400
A point where 2 or more straight lines meet.
What is Vertex
400
An angle that is 90 degrees exactly.
What is a RIGHT ANGLE
400
A plane shape with straight sides (We're calling you out, CIRCLE!) is called THIS...
What is a POLYGON?
400
None!
Don't press + or - , there's no question!
400
Draw various types of angles and try to find the degrees. Use a ruler or straightedge.
Don't press + or -! there's no question!
500
Lines that go forever and never intersect.
What are parallel lines?
500
when 2 lines are crossed by another line. The pairs of angles on opposite sides of the transversal but inside the 2 lines are called THIS.
What are ALTERNATE INTERIOR ANGLES
500
A flat shape with four straight sides (ahem, SQUARE and RECTANGLE) is called THIS....
What is a QUADRILATERAL
500
NONE!!
DON'T PRESS + OR - ! There's NO QUESTION!
500
Make flashcards!!! They are always a vivid and fun way to remember terms.
Don't press + or - ! There's no question! Thanks for playing!
