Quadratic expression / standard form
ax^2 + bx + c
Quadratic formula
If a quadratic equation is written in the form of ax^2+bx+c=0, then the solutions to the equation are given by
X=-b+_ b^2-4ac
———-2a———
Line segment
All points between two given points (including the given points themselves) a——b
Ray
Part of a line that has one end point
Acute angle
And angle whose measure is less than 90 degrees
Obtuse angle
An angle whose measure is more than 90 degrees but lass than 180 degrees
Complementary angles
Two angles whose sum is 90°
Supplementary angles
Angles that equal 180°
Congruent angles
Have the same angle measure
Vertical angles
The angles that are across from one another when two lines intersect
They are always equal
Corresponding angles
Are congruent
Alternate interior angles
Are congruent
Alternate exterior angles
Are congruent
