Proving Triangles Congruent
Triangles whose three corresponding sides are congruent must also be congruent.
What is SSS (Side-Side-Side)?
This is the second element on the periodic table.
What is Helium?
This is the number of vertex angles that an isosceles triangle has.
What is one?
"My name is Jeff."
What is 22 Jump Street?
This postulate tells us that if I is between H and J, then HI + IJ = HJ
What is the segment addition postulate?
Two pairs of congruent sides, including a pair of congruent angles.
What is SAS (Side-Angle-Side)?
This is the molecular formula for Sulfuric Acid.
What is H2SO4?
This theorem states that if two angles of a triangle are congruent, then the sides opposite those angles are also congruent.
What is the base angles theorem OR isosceles triangle theorem?
"Yo, Adrian!"
What is Rocky?
This is the name for any polygon that has a diagonal that can be drawn outside the shape itself.
What is concave?
This involves an included side, surrounded by two congruent pairs of angles.
What is ASA (Angle-Side-Angle)?
This is the name of the fourth state of matter, which is exists primarily at high temperature conditions such as stars.
What is plasma?
If a vertex angle of an isosceles triangle is 10 degrees, this is the measure of one of the base angles.
What is 85 degrees?
"Do or do not! There is no try."
What is Star Wars: Empire Strikes Back?
This is the term for two non coplanar lines, that by definition will never intersect.
What is skew?
This type of proof is the only one that requires that both triangles are right.
What is HL (Hypotenuse-Leg)?
What is normal force?
If an angle in an isosceles triangle measures 90 degrees, what is the measure of the other two angles?
What is 45 and 45?
"Houston, we have a problem."
What is Apollo 13?
This theorem tells us that if M is the midpoint of XY, then MX = 1/2XY.
What is the midpoint theorem?
This postulate doesn't prove that two triangles are congruent, but instead, similar.
What is AAA (Angle-Angle-Angle)?
This was the father of genetics, whose work on pea plants set the stage for our modern understanding of dominant-recessive inheritance patterns?
Who was Gregor Mendel?
The measure of a vertex angle is four times the sum of the base angles. This is the measure of the base angles.
What is 18 degrees?
"You got a dream... You gotta protect it. People can't do somethin' themselves, they wanna tell you you can't do it. If you want somethin', go get it. Period."
What is Pursuit of Happyness?
Coplanar lines that do not intersect are called this.
