Step-by-step explanation:

1). segment AB ≅ segment AE 1). Given

2). ΔBAE is isosceles 2). Definition of isosceles Δs

3). ∠ABC ≅ ∠AEB 3). Corollary to isosceles Δs theorem

4). segment BG ≅ segment EF 4). Definition of midpoints

5). segment BC ≅ segment ED 5) Given

6). segment CD ≅ segment DC 6). Reflexive property

7). segment BD ≅ segment EC 7). Property of sum of equals parts

8). ΔBGD ≅ Δ EFC 8). SAS postulate

9). ∠1 ≅ ∠2 9). Corresponding parts of congruent Δs

10). ΔCHD is isosceles 10). Corollary to isosceles Δs theorem

your answer would be 12
