Lines
Two lines that are the same distance apart and never touch
What is Parallel lines
Has an 90 degree angle
What is a right angle
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
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?
This is a movement of all points on a figure in a fixed distance “a” units in the x-direction and “b” units in the y-direction.
What is a translation
Lines that intersect to form a right angle
What is perpendicular
An angle that is less than 90 degrees
What is acute
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 hypotenuse legs or legs
This is a flip over a point, line, or plane
What is a reflection
This has one endpoint and continues in one direction
What is a ray
An angle that is greater than 90 degrees
What is an obtuse
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
Besides one angle you need this number of sides to prove a right triangle congruent
What is two
True or False : A rigid motion transformation can be a sequence of one or more transformations
What is true
One line that continues on both ends
What is a segment line
This is the number of degrees in a straight line
What is 180 degrees
If three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
What is SSS
The sum of the two acute angles in a right triangle.
90 degrees
A group of transformations that preserves distance and angles measures
What is Rigid Motion
Has a 90 degree angle
What is a right angle
Used to measure angles
What is a protractor
if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent
What is HL theorem
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 is an object with no depth or breadth, but only location.
What is a point
