|---|---|---|---|---|---|
| axiom | Euclid - common notions about arithmetic
🗑
|
||||
| lines either _______ or are __________ | Lines either intersect or they are parallel
🗑
|
||||
| Ray | Half a line with one endpoint included
🗑
|
||||
| Line Segment | A piece of line joining two point (and including the point)
🗑
|
||||
| Parallel lines | Lines that lie on the same plane and have NO points in common
🗑
|
||||
| Intersecting lines | Two lines lying on the same plane - they have a single point in common
🗑
|
||||
| Two rays with a common endpoint | Angle
🗑
|
||||
| Vertex of angle | point where two rays meet
🗑
|
||||
| Acute angle | An angle whose measure is between 0 & 90 degrees
🗑
|
||||
| Right angle | measures 90 degrees
🗑
|
||||
| Obtuse angle | measure between 90 and 180 degrees
🗑
|
||||
| "fat" or obese angle | Obtuse - bigger than 90 with "belly" hanging over
🗑
|
||||
| Straight angle | Horizon line is example - 180 degrees
🗑
|
||||
| Reflex angle | Larger than 180 degrees - to 360 degrees
🗑
|
||||
| Vertical angles | Pair of non-adjacent angles - formed by the intersection of two lines
🗑
|
||||
| Corresponding angles | Formed by transversal cutting through two parallel lines - have equal measures
🗑
|
||||
| Alternate interior angles | Have equal measures
🗑
|
||||
| Circle | the set of all points lying on a plane that are located
🗑
|
||||
| Radius | (blank)
🗑
|
||||
| Circle | A line forming a closed loop, every point on which is a fixed distance from a center point
🗑
|
||||
| Radius | The radius is the distance from the center to any point on the circle. It is half the diameter
🗑
|
||||
| Diameter | The distance across the circle. The length of any chord passing through the center. It is twice the radius
🗑
|
||||
| Circumference | The circumference is the distance around the circle.
🗑
|
||||
| Acute angle | Less than 90 degrees (little or "cute")
🗑
|
||||
| complementary angles | a pair of angles who, added together, are 90 degrees
🗑
|
||||
| "It's right to give compliments" | Remember that complementary angles equal one acute angle or 90 degree angle
🗑
|
||||
| Supplementary angles | Two angles, when added together, equal 180 degrees
🗑
|
||||
| If an angle measures x to zero degrees, represent its complement algebraically | Use "x" for one angle and "90-x" for the other angle; together they must add up to 90 degrees total
🗑
|
||||
| If an angle measures x to zero degrees, represent three times its complement algebraically | 3(90-x)
🗑
|
||||
| Write algebraic expressions to find the degree of measure of two supplementary angles | use "x" for smaller angle and "180-x" for larger angle
🗑
|
||||
| Use algebra to find measure of angles of traingle where only one angle measure is known | Use "180 - x - 30" for angle B, then 150 - x = measure of angle C (see Dug. p. 115)
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
