Point | show 🗑
|
||||
show | One dimension (length). A straight path that extends infinitely in both directions. Two points determine a line.
🗑
|
||||
show | A part of a line between two endpoints. A finite length.
🗑
|
||||
Plane | show 🗑
|
||||
show | Three or more points on the same line. Co (together) Linear (line).
🗑
|
||||
show | Three or more points that are NOT on the same line. You know that 3 points are non collinear when you cannot draw one line that contains all three of those points.
🗑
|
||||
Coplanar | show 🗑
|
||||
Compass | show 🗑
|
||||
show | A tool used to draw straight lines.
🗑
|
||||
Congruent | show 🗑
|
||||
show | The length of the segment between two points.
🗑
|
||||
Intersection | show 🗑
|
||||
show | A pair of angles (two) that form a straight line. These are adjacent and add up to 180 degrees.
🗑
|
||||
show | Next to one another. Two angles are adjacent when they share a common vertex and a common side.
🗑
|
||||
show | A common endpoint. The vertex of an angle is where the two sides of the angle converge or meet.
🗑
|
||||
Midpoint | show 🗑
|
||||
show | Two rays with a common vertex form an angle measured in degrees.
🗑
|
||||
show | An angle that measures between 0 and 90 degrees.
🗑
|
||||
show | An angle that measures between 90 and 180 degrees.
🗑
|
||||
Straight Angle | show 🗑
|
||||
show | A mark created using a compass. An arc is another name for a construction mark.
🗑
|
||||
show | Constant distance from the center of a circle to a point on the circle.
🗑

||||
Right Angle | show 🗑
|
||||
Supplementary Angles | show 🗑
|
||||
Complementary Angles | show 🗑
|
||||
show | A logical argument in which each statement you make is supported by a reason that is accepted as true.
🗑

||||
Equilateral | show 🗑
|
||||
show | Having equal angles.
🗑

||||
Right Triangle | show 🗑
|
||||
show | 3 sided Polygon. Interior angles always sum to 180 degrees.
🗑
|
||||
Isosceles Triangle | show 🗑
|
||||
Equilateral Triangle | show 🗑
|
||||
show | Matching parts of congruent figures.
🗑
|
||||
Pythagorean Theorem | show 🗑
|
||||
show | The largest side of a right triangle. This side is directly 0pposite the right angle.
🗑
|
||||
show | The same distance.
🗑
|
||||
Perpendicular Bisector | show 🗑
|
||||
Bisector | show 🗑
