100
No Equal Sides or Angles
What is Scalene
100

Number of angles in a triangle.

What is 3 angles

100

When 2 triangles have 3 pairs of congruent sides

What is SSS

100

When 2 objects share a side or an angle

What is the reflexive property?

100
Has two congruent sides called legs.
What is Isosceles Triangle
200
Two equal sides and angles
What is Isosceles
200
The value of all three angles in a triangle added together.
What is 180 degrees
200
If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
What is SAS
200

Angles that are across from each other at an intersection. The angles are congruent. 

What are Vertical Angles?

200
All three sides are congruent.
What is Equilateral Triangle
300
All sides and angles are equal.
What is Equilateral
300

When two lines intersect the opposite angles are congruent to each other.

What is vertical angles

300
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
What is ASA
300
The two sides of a right triangle that form the 90 degree angle.
What are the legs
300
All three angles equal 60 degrees.
What is Equiangular.
400
Has an angle whose measurement is greater then 90 degrees.
What is Obtuse
400
The little box in the corner of a triangle.
What is 90 degrees.
400
If two angles and the non-included side one triangle are congruent to two angles and the non-included angle of another triangle, then these two triangles are congruent.
What is AAS
400

The information that first goes in a proof

What is Given

400
The non congruent side of an isosceles triangle.
What is a base
500
All angles measure less then 90 degrees.
What is acute.
500

Angles on the opposite side of the transversal and inside the parallel lines

What are Alternating Interior Angles

500

Two right triangles that have a congruent hypotenuse and a corresponding, congruent leg are congruent triangles.

What is Hypotenuse Leg

500
Besides one angle you need this number of sides to prove a right triangle congruent?
