Geom Q2 (1.5-1.7)

QuestionAnswer
Angle Figure formed by two straight lines drawn from the same point
Sides Lines drawn in the angle
Vertex (vertices) Where the sides of the angle intersect
Between the other two letters Where is the letter of the vertex always written
Equal Two angles that can be made to coincide are
Bisector of the angle Line through the vertex of an angle which divides it into two equal parts
Half of the whole angle Each part formed by the angle bisector is
Size of the angle Depends on the amount of turning and not on the length of the pencil
Perigon Angle formed when the generating line makes a complete revolution
Straight angle An angle whose sides form one straight line extending through the vertex
Adjacent angles Two angles that have the same vertex and a common side between them
Right angle Each angle formed when two straight lines meet to make two equal adjacent angles
Right angle Half of a straight angle
All straight angles are equal Principle 12
Perpendicular Two lines that form right angle with each other
Foot of the Perpendicular Point that the perpendicular lines share
Acute angles Angle that is less than a straight line
Obtuse angles Angle that is greater than a right angle and less than a straight angle
Reflex angle Angle greater than a straight angle but smaller than a perigon
Oblique angles Acute, obtuse, and reflex angles and lines that have the position of the sides of any of these angles; lines that are not perpendicular or parallel;
Complementary Two angles that add up to a right angle
Supplementary angles Two angles whose sum is a straight angle
Vertical angles (opposite angles) Two angles not adjacent when two straight lines intersect

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.
