Section 5-7 Proving special quadrilaterals

Hi fellow honors geometry students.  I made up my own mini proofs that have to do with the section we're learning and took pictures of them completed.  Make sure you comment on my blog at the bottom!

Here is proving a Rectangle using parallelogram with congruent diagonals implies rectangle.  Other ways to prove Rectangles include: a parallelogram with at least one right angle or a quadrilateral with all four angles are right.

Proving Rhombi

• A parrallelogram with congruent consecutive sides
• Diagonals of parrallelogram bisect 2 angles of the parallelogram
• A quadrilateral with diagonals that are perpendicular bisectors.

That one's SO sloppy. my bad




Proving Squares
There's only one way to prove a square: it's a rectangle and a rhombus.

Proving Kites

• One diagonal is a perpendicular bisector (shown) 
• A quadrilateral with 2 pairs of congruent disjoint sides.

Proving Isosceles Trapezoids

• Trapezoid with congruent base angles
• Nonparrallel sides of a trapezoid are congruent
• Diagonals of a trapezoid are congruent

Alright, enjoy my blog!
