Classifying Triangles
No Equal Sides or Angles
What is Scalene?
Number of angles in a triangle.
What is "3 angles"?
3 corresponding sides of two triangles are congruent
What is SSS?
These are formed when we have two intersecting lines.
What is a set of vertical angles?
Has two congruent sides called legs.
What is Isosceles Triangle?
Two equal sides and angles
What is Isosceles?
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 an Equilateral Triangle?
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?
A set of congruent interior angles formed by parallel lines and a transversal.
What are alternate interior angles?
Mrs. Anderson's dog. (name or breed)
What is Tank? or
What is Sisko? or
What is a Newfie Mix? or
What is a Golden Retriever?
OR: any past dog...
Has an angle whose measurement is greater than 90 degrees.
What is Obtuse?
The congruent angles that are on the same side of the transversal when there is a set of parallel lines.
What are corresponding angles?.
If two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.
What is AAS?
When two congruent angles or two congruent segments are formed by using this.
What is a bisector?
Reason given when two triangles have a shared side.
What is the reflexive or symmetric property?
All angles measure less then 90 degrees.
What is acute?
An exterior angle of a triangle is equal to the sum of the non-adjacent interior angles. (which theorem?)
What is the 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?
When two lines meet and form a right angle (include symbol).
What are perpendicular lines?
The name of the angle between sides AB and BC.
What is Angle ABC?
