The name of this polygon is based on the relationship between its opposite sides.
What is a parallelogram?
These types of lines have equivalent slopes.
What are parallel lines?
These angles are congruent, found inside the parallel lines, and on opposite sides of the transversal.
What are alternate interior angles?
If I translated the point (4,2) using the rule T<-3,-3> then I would arrive at this location.
This line segment connects the midpoint to the opposite vertex of a triangle.
What is a median.
This quadrilateral has only two sides that are congruent and called legs.
What is an isosceles trapezoid?
When you reciprocate and negate the slope, you get this kind of line.
What is a perpendicular line?
This degree measure gives the sum of the exterior angles of a polygon with 312 sides.
What is 360 degrees?
If I rotated the point (3,2) 180 degrees clockwise, I would arrive at this location.
Where is (-3,-2)?
This line segment divides an angle into two congruent angles.
What are angle bisectors?
This polygon has perpendicular diagonals and 2 pairs of adjacent sides that are congruent.
What is a kite?
This line intersects two parallel lines.
What is a transversal?
The sum of these types of angles is 180 degrees and are located in parallel lines intersected by a transversal.
Same Side Interior Angles
If I reflected the point (4,2) across the x-axis, I would arrive at this location.
Where is (4,-2)?
This center of a circle is found from the intersection of the altitudes.
What is the Orthocenter?
This type of triangle is based on having an angle greater than 90 degrees and 2 congruent sides.
What is an obtuse, isosceles triangle?
The slope formula.
What is y2-y1 divided by x2-x1?
This value represents angle A.
How much is 125 degrees.
This is where A' is located after using the following composition of rigid motions:
T<0,5>o Rx-axis(2,2)
Where is (2,3)?
This is the center of a circle that intersects the vertices of a triangle.
What is a circumcenter?
This type of triangle exists when the sum of the square of 2 sides is congruent to the third side, squared.
What is a right triangle?
(Pythagorean theorem is only used for right triangles.)
The distance formula.
What is the square root of y2-y1 in parentheses squared plus x2-x1 in parentheses squared?
This is the sum of the interior angles for a nonagon.
These are all the types of rigid motions learned in Mr. McDonald's Geometry class.
Reflections
Translations
Rotations
The circumcenter of a triangle is located here when the triangle has a right angle.
What is the hypotenuse?
