Answer:
Step-by-step explanation:
3.AE = CE E is the midpoint of AC
4. ∠AEB = ∠CED Vertically opposite angles are equal
5. ΔAEB = ΔCED ASA congruence
The height of the given trapezoid is 7.5 m.
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area, 
Here 
is the lower base length and 
is the upper base length while h is the height.
Step 2:
In the given problem, 
and 
. Assume the height is h m.
The trapezoid's area 
So the height of the given trapezoid is 7.5 m.
Answer:
Congruent and isometries.
Step-by-step explanation:
Congruent meaning the shape is still the same size and shape
(which is true because translations and rotations don't change size or shape)
And isometries because it is one way of mapping points to a different location.
