100

A triangle that has no equal sides and no equal angles.

What is a scalene triangle

100
Number of angles in a triangle.
What is 3 angles
100

This postulate states that two triangles are congruent if all three sides of one triangle are congruent to all three sides of another triangle. 

What is SSS 

100
It states that the sum of the squares of the legs of a right triangle equals the square of the hypotenuse of a right triangle.
What is the Pythagorean Theorem?
100
All angles in an equilateral triangle are this many degrees.

What is 60 degrees

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
The sum of the two acute angles in a right triangle.
What is 90 degrees
200

All three sides in this triangle are congruent.

What is an equilateral triangle

300

In this triangle, all sides and all angles are equal.

What is an equilateral triangle

300

When two lines intersect to form an "x" 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

The name of the two sides of a right triangle that form the 90 degree angle.

What are the legs

300

True or False: An equilateral triangle is a type of isosceles triangle.

What is true about an equilateral triangle

400

This triangle has one angle that measures greater than 90 degrees.

What is an obtuse triangle

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
It states if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of another right triangle, then the triangles are congruent.
What is Hypotenuse-Leg Theorem
400

This triangle has angle measurements of 65°, 65°, and 50°. 

What is an isosceles triangle

500

All angles in this triangle measure less then 90 degrees and two of the angles are the same. 

What is an acute isosceles triangle.

500

Angle A and angle B make up a straight line. If angle A = 60 degrees and angle B = x + 25 degrees, what is the value of x?

What is 95 

500
If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
What is SSS
500
Besides one angle you need this number of sides to prove a right triangle congruent?
What is two.
500

In an isosceles triangle, one angle measures 45 degrees and another angle measures 90 degrees. The measure of the remaining angle is this number.

What is 45 degrees
