Geometry Basics

QuestionAnswer
Collinear Points Points on the same line
coplanar Points points on the same plane
Straight angle Angles who measures equal 180
Perpendicular Lines lines that form 90 degree
Perpendicular Bisector a line bisects a segment at a right angle
Complementar Angles = 90
Supplementary Angles = 180
Vertical Angles Verticals angles are congruent
Parallel Lines Same Slop
Transversal The line that goes through two lines
Alternate Interior Angles If 2 lines are II than alter. Inter angles are congruent
Alternate Exterior Angles If 2 lines II than alt ext angles are congruent,Corresponding angles if 2 lines II corresponding angles are congruents
Consecutive Interior If 2 lines are II then consecutive angles are supplementary (=180)
Slope formula y-y/x-x or m=
Negative Reciprocal Perpendicular lines flip the fraction and negate it
standard form ax + by = c
Slope intercept y=mx + B
Point Slope y-y1 = m(x-x1)
Vertical Line x=a
Horizontal line y=b
Midpoint Formula x2 + x1 / 2, y2+y1 / 2

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
