The part of a statement that follows the word "if."
What is the hypothesis?
100
Represented by a dot and a capital letter.
What is a point?
100
Pair of angles that add up to 90.
What are complementary angles?
100
A type of symmetry where the figure looks the same after being rotated more or less than 180 degrees.
What is rotational symmetry?
100
An "if, then" statement.
What is a conditional statement?
200
One instance that proves a statement wrong.
What is a counterexample?
200
Represented by a line with two arrows. Named with two capital letters or one lowercase letter.
What is a line?
200
Lines that have the same slope. These lines never intersect.
What are parallel lines?
200
A slide. The shape does not change. The size does not change.
What is a translation?
200
A pair of angles that create a straight line.
What is a linear pair?
300
The process of making a statement negative.
What is negation?
300
Represented by a line with two endpoints. Named with two capital letters.
What is a line segment?
300
Lines whose slopes are negative reciprocals. These lines make right angles when they intersect.
What are perpendicular lines?
300
A turn. The shape turns around a given point.
What is a rotation?
300
The longest side of a right triangle.
What is the hypotenuse?
400
Flips the conditional statement. q -> p
What is the converse?
400
Represented by a line with one endpoint and one arrow. Named with the endpoint first, then one other point.
What is a ray?
400
A line that crosses two or more lines in only one place. We work with them the most when dealing with parallel lines.
What is a transversal?
400
The figure BEFORE a transformation has happened.
What is a pre-image?
400
Looks exactly the same when rotated 180 degrees.
What is point symmetry?
500
Flips and nots the conditional statement. ~q -> ~p
What is the contrapositive?
500
Represented by a symbol and either three capital letters, the vertex, or a number. Can be acute, right, obtuse, or straight.
What is an angle?
500
Angles on the same side of the transversal and between the lines. These angles are supplementary.
What are same-side interior angles?
500
When a figure changes in size. This happens to your eyes when you go to the eye doctor.
What is a dilation?
500
Below is an example of what law?
If it rains, then the grass will be wet.
If the grass is wet, then it will grow.
If it rains, then the grass will grow.
