5. Trapezium
Trapezoid -No parallel
-One pair of
sides
parallel sides
Parallelo- -has pair of
-Twotwo pairs of
Kite congruent
parallel sides
gram
consecutive sides
6.
7. The base The diagonals
angles of a of an isosceles
trapezoid are trapezoid are
congruent congruent
If the base angles of a If the diagonals of a
trapezoid are congruent, trapezoid are congruent,
then the trapezoid is then the trapezoid is
isosceles isosceles
8. Formula:
180 = <A + <C
140 140
= <A + 40
40 180-40 = <A
40
140 = <A
140 = <A 40= <C
140 = <B 40= <D
Remember:
The base angles of a <A + <B + <C +< D = 360
trapezoid are congruent 40 + 140 + 140 + 40 = 360
9. 4 FORMULA:
6
? Median = ½
(b1+b2)
8
Median = ½ (b1+b2)
= ½ (4+8)
-Median = ½ (b1+b2) = ½ (12)
=6

11. -Opposite -Opposite
side are angles are
congruent congruent
-Any two -Diagonals divide
consecutive angles -The diagonals of
the parallelogram
of a parallelogram a parallelogram
into 2 congruent
are supplementary bisect each other
triangles.

13. Ratio – Comparison of two or more
quantities.
Simplifying ratio:
18:27 18/27 = 2/3 or 2:3
(Get the lowest term)
14. Proportion – equality
Principle of Proportion – the
of two or more ratio
product of the means is equal
to the product of the extremes
Ex: 2 :3 = 6 : 9
Terms: means
2 = 6
1 : 2 = 8 : 16 3 9
2x9=3x6
extremes
18 = 18
