Theorem Definitions
What are the five triangle theorems?
What are SSS, SAS, ASA, AAS, and HL
What is a Right Angle?
What is is an angle that bisects the angle formed by two halves of a straight line
If the hypotenuse and leg of one right triangle are congruent to the corresponding parts of another right triangle, and the right triangles are congruent. What Method Am I? (This is only for Right Triangles ONLY)
What is HL
If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, and the triangles are congruent. What is this method called?
What is SAS
What is Reflexive Property?
What is A quantity is congruent(equal) to itself. A=A
What is the Mid-Segment Theorem?
What is The segment connecting the midpoints of two sides of a triangle is parallel to the third side and is half as long.
Let's Have A Little Fun, Shall We? Which classic series does Ms. Mosby prefer - Star Trek or Star Wars?
What is Star Trek?
If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, and the triangles are congruent. What is this method called?
What is ASA
What is Symmetric Property?
What is If a=b, then b=a
True Or False: All Right Angles Are Congruent.
What is True.
This Method works fine to show that triangles are the same SHAPE (similar), but does NOT work to also show they are the same size, thus congruent! What Method Am I?
What is AAA
If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, and the triangles are congruent. What is this method called?
What is AAS
What is Transitive Property?
What is If a=b and b=c, then a=c
Let's Have A Little Fun, Shall We? 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?
An Envelope
Why Theorem SSA Doesn't Work?
What is SSA is not enough to prove congruence.
What does HL Means?
What is If two right-angled triangles have their hypotenuses equal in length, and a pair of shorter sides are equal in length, then the triangles are congruent.
This is NOT a universal method to prove triangles congruent because it cannot guarantee that one unique triangle will be drawn!! What method am I?
What is SSA
What is Alternate Interior Angles?
What is If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.
Let's Have A Little Fun, Shall We? What runs but never walks; has a mouth but never eats and has a bed but never sleeps?
What is a River?
What abbreviation helps us states that if two or more triangles are proven congruent by any method then all of their corresponding angles and sides are congruent as well? (This also is especially useful in proving various geometrical triangles and polygons)
What is CPCTC(Corresponding parts of congruent triangles are congruent)
