Quadrilaterals
If polygon with four sides then the sum of the measures of their angles equal 360
Parallelogram
If it is a quadrilateral has two sets of parallel sides/opposite sides are parallel then parallelogram
If opposite angles are congruent then parallelogram
If diagonals bisects each other then it is a parallelogram
Properties of a parallelogram
Quadrilateral
Opposite angles are congruent
Connective angle are supplements
The dialognals bisects each other
Opposite sides are parallel
Two sets of parallel sides
Theorums parallelogram
If a quadrilateral sides are congruent then parallelogram
If a quad. And opposite angles are congruent then parallelogram
If a quad. And consecutive angles are supplement then parallelogram
If a quad. And diagonal bisects each other then parallelogram
If a quad. Has one set of sides that are both parallel and congruent then parallelogram
Rectangle
If a parallelogram and equianglar then rectangle
If a parallelogram and each angle is a right angle then rectangle
If a parallelogram and dianogals are congruent then retangle
Rhombus
If a parallelogram and equilateral then rhombus
If a parallelogram and dialogas are perpendicular then rhombus
If a eqaliteral retangle then square
If a equianglar rhombus then square
Trapezoid
If a quad. And has exactly one set of parallel sides then trap.
T or F….
Base of a trap. Can be congruent to the other base
FALSE
T or F…
Can a trap. Have 2 sets of parallel lines
False
T or F…
A trap. Legs can be congruent
True
Isosceles trap.
If a trap. And legs are congruent then isosceles trap.
If a trap. And base angles are congruent then isosceles trap.
If a trap. And dialognals are congruent then isosceles trap.
Kites
If a quad. And two sets of consecutive sides are congruent then kite
If a trap. And dialognals are perpendicular then kite
Median trap.
If a segement that joins the midpoint of the legs then median trap.
If a trap. Is parallel to the bases then a median trap.
If a median trap. Then length is the average of bases
Midsegement
If a segement is parallel to the 3rd line and half as long as the 3rd line then midsegement
Theorems of midsegement hypotenuse
If the midsegement hypotenuse joins two sides of a triangle then it is parallel to the 3rd line
If the midsegement hypotenuse joins two sides of a triangle then it is half as long as the 3rd side
