What is the AA, Angle-Angle, similarity theorem?
The theorem states that when you have two congruent triangle angles then must have similar triangles.
100
State the SSS similarity theorem.
If two triangles have the same proportion across all three corresponding sides then the triangle is similar.

What was the first US State?
Delaware
200
What is the Value of x?
X= 30
200
Are these triangles similar?
Yes because of vertical angles and alternate interior angles.
200
State the SAS similarity theorem.
If two corresponding side legs of triangles are proportional and the angle in between is congruent then the triangles are similar.
200
State the triangle proportionality theorem.
If a triangle is cut by a line that is parallel to the the base then it divides the triangle proportionally.

Explain why this image is wrong.
AA similarity does not work on anything but triangles.
300
Show the triangles are similar and write a similarity statement.
Using SSS we know they are all the same proportion.
300
State the triangle angle bisector theorem.
If a ray bisects an angle of a triangle, then it divides the opposite sids of the triangle into proportional pieces.

Identify the value of y in these similar triangles
y=9
400
Explain the reason this image is wrong.
The proportion is wrong as it should be 9 over x.
