100
No Equal Sides or Angles
What is Scalene
100

The sum of the 3 angles in a triangle.

What is 180 degrees

100

The postulate/shortcut you can use when 3 sides are congruent.

What is SSS

100

The name of the side that is opposite a right angle in a right triangle.

What is the hypotenuse?

100

If a vertex angle in an isosceles triangle is 100 degrees then each base angle must be how many degrees?

What is 40 degrees.

200

At least two equal sides and angles

What is Isosceles

200

The value of a third angle in a triangle if one angle is 50 degrees and another is 70 degrees.

What is 60 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

The relationship between the two acute angles in a right triangle.

What is complementary.

200

The measure of each angle in an equilateral triangle.

What is 60 degrees

300

All sides and angles are equal.

What is Equilateral and Equiangular or just regular.

300
When two lines intersect the opposite angles are equal 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

What we call the two sides of a right triangle, that are not the hypotenuse.

What are the legs

300

The base angle measures in an isosceles right triangle.

What is 45 degrees.

400

Has an angle whose measurement is greater than 90 degrees.

What is Obtuse

400

The measure of the smallest angle in a triangle if the three angles are in the ratio of 4:5:6.

What is 48 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 shortcut to prove congruence that only works with right triangles.

What is Hypotenuse-Leg Theorem

400
The non congruent side of an isosceles triangle.
What is a base
500

All angles measure less than 90 degrees.

What is acute.

500

The measure of an exterior angle to a triangle where the two non-adjacent angles are 30 degrees and 80 degrees.

What is110 degrees

500

This shortcut does not work because you can actually create different triangles when given just this information, a variation of this only works with right triangles.

What is SSA

500

The measure of the 2 acute angles in a right triangle if they are in the ratio of 4:5

What is 40 and 50 degrees

500
The point where two congruent legs come together.
What is Vertex Angle
