Proof Stuff

When two lines are cut by a transversal, the angles that are formed in corresponding position at each intersection

When two lines are cut by a transversal, the two angles on the same side of the transversal between the two lines

When two lines are cut by a transversal, the two angles on the opposite sides of the transversal between the two lines

When two lines are cut by a transversal, the two angles on the opposite sides of the transversal outside of the two lines

When two lines are cut by a transversal, the two angles on the same side of the transversal outside of the two lines

Two lines on the same plane, that, when extended infinitely far in either direction, never intersect, they have also have the same slope

Two lines that intesect to form a right angle

Two lines on seperate planes that never intersect

The X method

Y=MX+B

The negative of the inverted fraction 5/2 becomes -2/5. Perpendicular lines have opposite reciprocal slopes

Example that proves the statement false

Addition on both sides of equation

Subtraction on both sides of equation

Multiplcation on both sides of equation

Division on both sides of equation

A(B+C) becomes AB+AC

A=B, 2B+4A=6, 2A+4A=6. When you replace a value in an equation with something you know its equal to.

Mirror-A=A

If A=B, then B=A

If A=B, B=C, Then A=C,

Two angles opposite each other in an intersection

Two angles that add up to 90

Two angles that add up to 180

The space measured in degrees between two intersecting lines

A set of points equal distance to a center point
