Answer:
A C E F G
Step-by-step explanation:
Use Pythagoras' Theorem a² + b² = c² (where a and b are the legs and c is the hypotenuse of a right triangle) to calculate the lengths of the sides
DE = √(2² + 4²) = 2√5
EF = √(1² + 4²) = √17
GF = √(5² + 10²) = 5√5
DG = √(1² + 5²) = √26
A) DE is parallel to GF
C) EF = √17
E) Quad is NOT an isosceles quadrilateral (as EF ≠ DG)
F) DG = √26
G) Quad IS a trapezoid ( as it has one pair of parallel lines)
