Quadrilaterals Principles

Question 1

P-Gram

Answer 1

Opposite Sides Parallel
Opposite sides congruent
Opposite angles congruent
Consecutive angles supplementary
Diagnols Bisct each other

Question 2

Rhombus

Answer 2

P-Gram
Four congruent sides
Diagnols are perpendicular
Diagnols bisect opposite angles

Question 3

Rectangle

Answer 3

P-Gram
Four right angles
Diagnols are congruent

Question 4

Square

Answer 4

P-Gram, Rhombus, Rectangle

Question 5

Trapezoid

Answer 5

Only one pair of opposite sides are parallel (called bases)
Consecutive angles are supplementary
**
Midgement of a Trapezoid:
A midsegment of a trapezoid connects the midpoints of the legs. This segment is equal to the average of the two bases.

Question 6

Isosceles Trapezoids

Answer 6

Trapezoid
Non-parallel sides (legs) are congruent
Diagnols are congruent
Base angles are congruent
Opposite angles are supplementary
