Postulates
Two sides and the included angle
What is the SAS criterion?
This is also known as the mirror line.
What is the line of reflection?
The postulates used to prove triangle congruence for acute triangles, excluding right triangles.
What are the SSS, SAS, ASA, and AAS criteria?
What occurs once in a minute, twice in a moment and never in one thousand years?
What is the letter M?
Three pairs of sides of two triangles are congruent
What is the SSS criterion?
The smallest angle a figure has to turn to coincide with itself.
What is the degree of rotational symmetry?
This is not a postulate at all, but represents two sides and the non-included angle.
What is the SSA criterion?
He was a member of Paranormal State, a ghost hunting team.
Who is Mr. Grande?
Two pairs of angles and the included side
What is the ASA criterion?
The number of rotations for an image to be rotated so that it looks exactly like the original figure.
What is the order of rotational symmetry?
Two angles and the included side.
What is the ASA criterion?
I start with the letter "e" and end with the letter "e" and I usually contain 1 letter, but I am not the letter "e"! What Am I?
What is an envelope?
Two pairs of angles and the non-included corresponding side
What is the AAS criterion?
This property is used when two triangles have a shared side. For example, we write AC is congruent to AC to prove congruence for triangles ABC and ADC.
What is reflexive property?
Two angles and the non-included side.
What is the AAS criterion?
Two lines that intersect to create a 90ยบ angle.
What is perpendicular?
It starts out tall, but the longer it stands, the shorter it grows. What am I?
What is a candle?
The hypotenuse and a leg of two right triangles are congruent
What is the HL criterion?
This means that all the parts of one triangle are equivalent to the corresponding parts of another triangle.
What are congruent triangles?
This postulate is used for Right Triangles ONLY
What is the hypothenuse-leg (HL) postulate?
The line segment that divides an angle into half.
What is the angle bisector?
Name three consecutive days without using the words Wednesday, Friday, and Sunday?
What is yesterday, today, and tomorrow?
