Computer lab working on systems of equations

8. Thursday – pick up your texts
Warm Up – make a flow chart describing what we know about:
Quadrilaterals
Parallelograms
Rectangle
Rhombus
Square
Do also for triangles, kites, and trapezoids

9. Quadrilaterals
Closed, planar four sided shape, sides are all straight

10. Parallelograms Quadrilateral with: Two sets of parallel sides
Opposite sides are congruent
Opposite angles are congruent
Diagonal bisect each other
Diagonals form two pair of congruent triangles

11. Rhombus Parallelogram with: All sides are congruent
Diagonals are perpendicular
Diagonals form 4 congruent right triangles

12. Rectangles Parallelogram with: Perpendicular corners
Parts of diagonals are all congruent
Diagonals form two pairs of congruent isosceles triangles

13. Square Has all the properties of a Rectangle and Rhombus
Four congruent right isosceles triangles

14. Other Quadrilaterals Trapezoids: Isosceles trapezoids: Kite
Quadrilateral with exactly one pair of sides parallel
Isosceles trapezoids:
Have congruent non parallel legs
Two pairs of congruent angles
Kite
Two pair of adjacent sides are congruent
Long diagonal bisects short diagonal
One pair of opposite angle are congruent
Diagonals are perpendicular
Two pair of congruent right triangles

15. Triangles Based on side length: Based on angles
Scalene – all sides different length
Isosceles – one pair of sides are congruent
Equilateral – all sides congruent
Based on angles
Obtuse – one angle > 90 degrees
Acute – all angles < 90 degrees
Equiangluar – all angles = 60 degrees
Right – one angle = 90 degrees
