Transformations
When looking at a transformation on a coordinate plane, THIS is how you determine which shape is the old/preimage and which shape is the new/image
What is image/new has prime symbols?
This is the type of concurrency created by perpendicular bisectors
What is the circumcenter?
This is the number of degrees in a circle
This is the name of a triangle in which all 3 angles are less than 90 degrees
What is an acute triangle?
This is the number of sides in a quadrilateral
What is 4?
Explain what the following transformation means
(x,y) -> (x+2, y-4)
What is translate 2 to the right and 4 down?
This is the point of concurrency created by altitudes
What is the orthocenter?
This is half the length of the diameter
What is a radius?
This is the name of the longest side of a right triangle
What is the hypotenuse?
This is the sum of the interior angles of a quadrilateral
What is 360 degrees?
This is a transformation that does NOT preserve distance/congruence
What is a dilation?
This is the name of a segment or line that splits an angle into two congruent pieces
What is an angle bisector?
This is the radius of the following circle:
(x-2)^2 + (y+4)^2 = 36
What is 6?
This is the theorem that is used to find missing side lengths in a right triangle (BOTH NAME AND FORMULA)
What is the Pythagorean Theorem? a^2+b^2=c^2?
This is the measure of an angle in a parallelogram if its consecutive angle is 150 degrees
What is 30 degrees?
This is the new coordinate of point A (5,6) after being reflected over the x-axis
What is A'(5,-6)?
These are the two types of concurrency that are ALWAYS inside the triangle (regardless of whether the triangle is acute, obtuse, or right)
What is the incenter and the centroid?
This is the number of degrees of the intercepted arc if the inscribed angle (creating the arc) is 45 degrees
What is 90 degrees?
This is the property that is often used to show that a shared side between two triangles is congruent to itself
What is the reflexive property?
This is one of the two characteristics that a rectangle has that a parallelogram does not?
What is "four right angles" or "congruent diagonals"?
This is the quadrant that point (-3,-5) would end up in after a 90 degree clockwise rotation
What is Quadrant II?
This is the length of the entire median if the distance from the midpoint to the centroid is 5
What is 15?
This is the formula for arc length
What is the circumference * theta/360?
dpi * theta/360
2rpi * theta/360
This is the trig function that can be used when given an opposite and adjacent side
What is tangent?
This is the formula for the area of a kite or rhombus
What is A=1/2(d1xd2)?
