100

a squared plus b squared is equal to c square

Pythagorean Theorem

100

This will result in a right angle being formed between objects. Slopes are opposite and reciprocal

Perpendicular

100

Two sides and an included angle are marked congruent

SAS

100

A triangle that has all the sides the same and all the angles equal to 60 is two things

Equilateral and Acute

100

This center is created by Altitudes

Orthocenter

200

d is equal to the square root of the sum of the squares of the differences of the x-values and y-values

Distance Formula

200

When some thing is split into two, equal pieces

Bisect

200

Two angles and an included side are marked congruent

ASA

200

A triangle that has a 90 degree angle and two sides the same is two things

Right and Isosceles

200

This center is created by Medians

Centroid

300

The average between two x-values and two y-values can be found with this formula, giving you a point equally between the two

Midpoint Formula

300

When two things are on the same plane, but will never intersect... the slopes are the same

Parallel

300

Two angles and a non-included side are marked congruent

AAS

300

A triangle with not a single side the same, and one angle is slightly bigger than 90 is two things

Scalene and Obtuse

300

This center is created by Angle Bisectors

Incenter

400

The change is the y-values is over the change in x-values and set equal to an m-value

Slope Formula

400

When an object is mathematically the same, in geometry it is considered

Congruent

400

All three sides are marked congruent

SSS

400

A triangle with two sides the same, and the vertex angle is 40 degrees

Acute and Isosceles

400

This center is created by PerpendicularBisectors

Circumcenter

500

What's the best first thing to do any time you use a formula

Label

500

Three lines meet at a common intersection 

Concurrent Lines

500

A right angle, the opposite side and any other side are marked congruent

HL

500

This Theorem allows you to find any angle in a triangle if at least two are known. What is it and what is the "set-up"

Triangle Sum Theorem and the sum in 180

500

What's the relationship of the medians in a Centroid situation?

Proportional: 1/3 vs 2/3
