Classify Triangles
No Equal Sides or Angles
What is Scalene
Number of angles in a triangle
What is 3 angles
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
Has two congruent sides called legs
What is Isosceles Triangle
The value of all three angles in a triangle added together
What is 180 degrees
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
The sum of the two acute angles in a right triangle
What is 90 degrees
All three sides are congruent
What is Equilateral Triangle
All sides and angles are equal
What is Equilateral
When two lines intersect the opposite angles are equal to each other
What is vertical angles
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
The two sides of a right triangle that form the 90 degree angle
What are the legs
All three angles equal 60 degrees
What is Equiangular
Has an angle whose measurement is greater then 90 degrees
What is Obtuse
The little box in the corner of a triangle
What is 90 degrees
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
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
The non congruent side of an isosceles triangle
What is a base
All angles measure less then 90 degrees
What is acute
An exterior angle of a triangle is equal to the sum of the opposite interior angles
What is Exterior Angle Theorem
If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent
What is SSS
Besides one angle you need this number of sides to prove a right triangle congruent
What is two
The point where two congruent legs come together
What is Vertex Angle
