What does SAS Means?
What is SAS Means if two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent.
100
If three sides of one triangle are congruent to three sides of another triangle, and the triangles are congruent. What is this method called?
What is SSS
100
How many theorems we use to prove that a triangle is congruent?
What is Five. We Use 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
100
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

What does SSS Means?
What is If three pairs of sides of two triangles are equal in length, then the triangles are congruent.
200
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
200

What is the triangle sum theorem?

The interior angles of a triangle add to 180 degrees.

What is 3?

What does ASA means?
What is If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent.
300
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
300
True Or False: All Right Angles Are Congruent.
What is True.
300
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
400
What Does AAS Means?
What is If two pairs of angles of two triangles are equal in measurement, and a pair of corresponding non-included sides are equal in length, then the triangles are congruent.
400
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
400
What is Transitive Property?
What is If a=b and b=c, then a=c
400

Why Theorem SSA Doesn't Work?
What is SSA is not enough to prove congruence.
500
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.
500
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
500
What is Alternate Interior Angles?
What is If two parallel lines are cut by a transversal, then the alternate interior angles are congruent.
500

What mathematical instrument allows you make an angle on a piece of paper?

Protractor

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)
