What is Scalene
Number of angles in a triangle.
What is 3 angles
Side Side Side
What is SSS
Describe this transfromation
(x, y) —> (3x, 3y)
What is dailation factor of 3
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
Describe this transformation
(x,y) — > (x+1, y - 4)
What is
translation one right and 4 down
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
A transformation that does not change the size or shape of a figure
What is a rigid transformation
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
Describe the transformation
(x,y) —> (-x, -y)
What is
rotation 180 degrees
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
Describe the transformation
(x,y) —> (-x,y)
What is
reflection across the y axis
