Question

Can someone help with geometry please?
Equation and drawing will be posted below.

Answer 1

Delta? Maybe you mean triangle of Abe and triangle of DCE? :)

Answer 2

1. AE=≈DE Given
2. angle A =≈ angle D Theorem 9 (If two side of a triangle congruent then the angle in front of them also congruent)
3. AB=≈DC Given
By postula side, angle, side (side AB=≈DC, angle A =≈ angle D, side AE=≈DE ) then
triangle ABE and triangle DCE are congruent :)

Answer 3

Yeah thats what I meant haha

Answer 4

Thank you!
