Definition
Abscissa
3-7
The first number in the ordered pair is the x-coordinate or abscissa
Converse
3-5
If you reverse the parts of the Pythagorean Theorem, you have formed its converse.
Coordinate Plane
3-7
Recall that you can locate a point by using a coordinate system similar to the grid used by the mountain biker. It is called a coordinate plane.
Hypotenuse
3-5
the two shortest lines on a right triangle
Ordered Pair
3-7
Any point on the coordinate plane can be graphed by using an ordered pair of numbers.
Ordinate
3-7
Any point on the coordinate plane can be graphed by using an ordered pair of numbers
Origin
3-7
The origin is the point of intersection of the two number lines.
Perfect Square
3-1
Numbers such as 1, 4, 9, 16, and 25 are called perfect squares because they are squares of integers
Pythagorean Theorem
3-5
The Pythagorean Theorem describes the relationship between the lengths of the legs and the hypotenuse for any right triangle
Quadrants
3-7
Quadrants are four sections of the coordinate plane.
Radical Sign
3-1
A square root of a number is one of its two equal factors.
X-Axis
3-7
Goes sideways.
X-Coordinate
3-7
The first number in the ordered pair is the x-coordinate or abscissa
Y-Axis
3-7
Goes up and down.
Y-Coordinate
3-7
The second number is the y-coordinate or ordinate.

Coordinate Plane
Hypotenuse
3-5
The hypotenuse is the side opposite the right angle. It is the longest side of the triangle.
Irrational Number
3-4
Numbers that are not rational are called irrational numbers
Legs
3-5
the two shortest lines on a right triangle
Ordered Pair
Ordinate
The symbol √􏰀, called a radical sign
