What is SSS
100

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

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

200
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 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.

What is Star Trek?

300
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 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

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.

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)
