Quadrilaterals
What is a four sided polygon called?
Quadrilateral
What other quadrilateral(s) can a parallelogram be?
Quadrilateral
What is a right angle?
an angle that measures at 90 degrees
What does congruent mean?
same or equal
What does reflection mean or do?
A flip over a line that reflects an image the same distance away from the line of reflection
What is a quadrilateral with one pair of parallel sides?
trapezoid
True/false? can a rhombus EVER be a square?
True, but only sometimes
What is an acute angle?
Any angle that measures less than 90 degrees
What is the sum of all the interior angles in a quadrilateral?
360
What does translation mean or what does it do?
A transformation that slides a figure horizontally or vertically. Every point in the figure also needs to move when translating.
What is a quadrilateral with 4 equal sides and 4 equal angles?
square
How many quadrilaterals are there on the quadrilateral family tree?
six quadrilaterals
What is an obtuse angle?
Any angle that measures over 90 degrees
What is the sum of all interior angles in a polygon?
180
If the polygon BEN had the points B(-8,5), E(-2,1), and N(-3,-4), where would the vertices be if it were to be reflected by the y-axis?
B(8,5), E(2,1), N(3,-4)
What are the characteristics of a parallelogram? (get at least 3)
opposite sides equal, opposite sides parallel, opposite angles congruent, and diagonals that bisect each other.
What quadrilaterals can a rectangle be?
parallelogram and quadrilateral
What is a polygon?
Any closed two-dimensional figure with three or more straight sides
True/False? any angle that measures less than 90 degrees is an obtuse angle.
false
If the figure THE had the points T(-3,-2), H(2,-1), and E(-4,-8), where would the vertices be if it were to be reflected by the x-axis, then translated 2 units right, and 4 units up?
T(-1,6), H(4,5) E(-2,12)
Which quadrilateral has all sides congruent, opposite sides parallel, and diagonals that meet at a right angle? (perpendicular)
rhombus
True/false, can a rhombus be a rectangle?
false
What does perpendicular mean?
If the interior angles of a triangle measures 33 and 59, how much does the third angle measure?
88
If the quadrilateral COOL had the points C(-6,4) O(-4,7), O(-2,4), and L(-4,1), where would the vertices be if it were to be reflected by the y-axis, then translated 4 units horizontally, and -1 unit vertically?
