Side Side Side

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
Has two congruent sides called legs.
What is Isosceles Triangle
200

A triangle with at least two equal sides and angles

What is an Isosceles triangle?

200

The sum 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 are congruent.
What is Equilateral Triangle
300

A triangle with all sides and angles are equal

What is an Equilateral/Equiangular triangle?

300

When two lines intersect, the nonadjacent angles are equal to each other.

What is the vertical angles theorem?

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

A triangle that has an angle whose measurement is greater than 90 degrees.

What is an Obtuse triangle?

400

The symbol that represents a right angle

What is a square?

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

A triangle with all angles measure less than 90 degrees

What is an acute triangle?

500

An exterior angle of a triangle is equal to the sum of the remote interior angles.

What is the Exterior Angle Theorem?

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?
