What is the general form for the transitive property?

If a=b and b=c, then a=c

What is special about vertical angles?

They are congruent

100

Same side interior angles are...

Supplementary

What is the converse of the alternate exterior angle theorem?

If two lines cut by a transversal make congruent alternate exterior angles, then the lines are parallel.

200

What property is the following


If a=b, then b=a

Symmetric Property

200

If two angles are congruent and supplementary, they must be what type of angle?

Right

200

Alternate interior angles are...

Congruent

How do you know when to use the alternate interior angles theorem or when to use its converse?

When proving congruent A.A.I's, use the regular.

When proving parallel lines, use the converse.

Given line AD with collinear points B and C so that AB = CD, prove that AC = BD

AB = CD

BC = BC

AB + BC = BC + CD

AB + BC = AC, BC + CD = BD

AC = BD

Given angles 1, 2, and 3, we know that angles 1 and 2 are complementary.  Angles 2 and 3 are also complementary.  Prove that Angle 1 is congruent to angle 3.

If 1 + 2 = 90 and 2 + 3 = 90, then 1+2 = 2+3.

Subtract 2 from each side and youre pretty much done

In pool, when a ball is banked off a side, it bounces off at the same angle it hit the wall (made by the path of the ball and the line perpendicular to the side).  If the ball hits the wall at a 40 degree angle, find the values of x and y

(I will make the diagram on the board)

x = y = 50

500

Find x and y

x=16

y=20

What values for x and y make the lines parallel?

x = 28, y=23
