Classifying Triangles
Number of angles in a triangle.
What is 3 angles
All three sides of a triangle are congruent
What is SSS
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
Two sides and the included angle 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 Regular
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
