Classifying Triangles
The total degrees found in a triangle
What is 180 degrees?
Number of angles in a triangle.
What is 3?
This three letter acronym is not a theorem for triangles?
What is A-S-S, or A-A-A?
It means the sum of the angles totals 90 degrees
What is Complimentary?
The sum of the angles in a right triangle totals 180 degrees.
What is Triangle Sum Theorem?
These triangles contain a 90 degree angle?
What are right triangles?
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?
when two lines intersect, the angles opposite each other are congruent, meaning they have equal measures.
What is the Vertical Angle Theorem?
All sides and angles are equal.
What is Equilateral?
When two lines intersect the opposite angles are equal to each other.
What are 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?
This theorem states that when two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent
What is Alternate Interior Angle Theorem?
All angles measure less then 90 degrees.
What is acute?
These angles total 180 degrees
What are supplementary angles?
If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
What is SSS?
This side is the longest side in a right triangle and opposite the 90 degree angle
What is the hypotenuse?
a squared plus b squared equals c squared
What is the Pythagorean Theorem?
These angles are in the same position when parallel lines are cut by a transversal.
What are corresponding angles?
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?
This congruence theorem states is for RIGHT TRIANGES ONLY!
The congruence theorem, which states that if two angles and a non-included side of one triangle are congruent to the corresponding two angles and non-included side of another triangle, then the two triangles are congruent.
What is Hypotenuse Leg Congruency Theorem?
