Geo Tools
Tool used to draw and measure angles
What is a protractor?
Two angles that add to 180.
What are supplementary angles?
The reason on the first line in any two column proof
What is given?
This type of transformation has a vector to indicate how it has moved.
What is translation?
This type of quadrilateral has two pairs of parallel sides
What is a parallelogram?
This is how to find the point in the middle of two other points.
What is [(x2-x1)/2, (y2-y1)/2]
These are the three types of transformations.
What are rotations, translations and reflections?
The reason we can say AB = CD if AB ≅ CD.
What is definition of congruent?
This type of transformation has order and magnitude to tell how it was moved.
What is a rotation?
This type of quadrilateral has only one pair of parallel sides
What is a trapezoid?
This is the fractional distance between 2 and 8, if you’ve traveled one-third of the way.
What is 4?
This is how you calculate the surface area of a rectangular prism.
What is 2(LxW + WxH + HxL)?
What is a counterexample?
If you reflect an image across the line y=x, you change each point (x,y) to this.
What is (y,x)?
A kite has this many lines of symmetry.
What is one?
This formula is used to calculate the distance between two points without having to use the Pythagorean Theorem.
What is the square root of (x2 - x1)^2 + (y2 - y1)^2?
This is the starting image before it's been transformed.
What is the pre-image?
"A figure is a square if and only if it is a rectangle and a rhombus" is an example of this type of statement.
What is a biconditional?
If you translate a shape 3 units down and 4 units right, this is the translation vector.
What is <4,-3>?
This quadrilateral has four right angles, opposite sides that are equal, and diagonals that bisect each other.
What is a rectangle?
The distance between the points (3, 4) and (7, 1) on a coordinate plane.
What is 5?
Two angles that are on opposite sides of a transversal and on the outside of the parallel lines
What is alternate exterior angles?
If a conditional statement is true, this is the only other type of statement that is guaranteed to be true.
What is the contrapositive?
A 90-degree counterclockwise rotation moves the point (x,y) to this.
What is (-y,x)?
These three shapes have diagonals that are perpendicular to each other.
What are rhombus, square and kite?
