What's That Graph?
100
two lines that never intersect and lie in the same plane
What is parallel
100
any angle whose measure is greater than ninety degrees but less than one hundred eighty degrees
What is an obtuse angle
100
any triangle that has at least two sides that are congruent to each other
What is isosceles
100
The property that states, If a = b, then b = a
What is the symmetric property
100
the change in the y coordinates of two points on a line divided by the change in the x coordinates of two points on the same line
What is the slope
200
points in a plane that form a line
What is collinear
200
the point at which two sides of an angle meet
What is the vertex
200
the area of a triangle
What is the base times the height, divided by two
200
The property that states, If a number j exists, then j = j.
What is the reflexive property
200
the point at which the graph of a line intersects the y-axis on the coordinate plane
What is the y-intercept
300
two lines or segments that intersect each other at four right angles
What is perpendicular
300
"If two lines are parallel cut by a transversal, then these angles are congruent". They lie in between the two parallel lines.
What is alternate interior angles
300
what results when all three pairs of corresponding sides are congruent, and all three pairs of corresponding angles are congruent
What are congruent triangles
300
the property that states, If a = b, and b = c, then a = c.
What is the transitive property
300
a form of an equation that represents a line y = mx + b
What is the slope-intercept form of a line
400
a line that intersects any two other lines
What is a transversal
400
"If two lines are parallel cut by a transversal, the these angles are supplementary".
What are consecutive interior angles
400
an angle that lies outside a triangle that is formed by extending a side of the triangle
What is an exterior angle
400
The property that states, If a is a number in a +b, and if a = c, then c + b.
What is the substitution property
400
the square root of the sum of the squares of the y coordinates of two points' difference, and the x coordinates of those two points' difference
What is the distance between two points
500
The conditional statement that says, "If two line segments exist, then their measures can be added together."
What is The Segment Addition Postulate
500
A pair of angles that are created opposite one another, by the intersection of two lines
What are vertical angles
500
The conditional statement that says, "If a triangle is a right triangle, then the two acute angles are complementary
What is The Triangle Sum Corollary
500
If a(b + c), then ab + ac.
What is the distributive property
500
the form of a line represented by Ax + By = C
What is the standard form of a line
