Block 5: Trapezoid and Isosceles Trapezoid
Trapezoid
Base: Parallel sides of a trapezoid
Legs: Nonparallel sides of a trapezoid
Isosceles Trapezoid
Block 6: Trapezoid and Isosceles Trapezoid Examples
Example
So, if angle C is 65 then angle F is 65. Angles D plus angle C equals 180.
So 180 minus angle C equals 115. Angle D is 115 then angle E is also 115.
Block 7: Kite
Kite
A quadrilateral with two pairs of consecutive sides congruent and no opposite sides congruent
Block 8: Kite Example
Example
Since the diagonals are perpendicular, the point where they meet is right angle (angle 1)
Angle three is 52 because it is corresponding to each other
Each triangle inside the kite equals 180.
Angle 1 plus Angle 3 plus Angle 2 equals 180
90 + 52 + angle 2 = 180
142 + angle 2 = 180
Subtract 142 from 180
angle 2 = 38
