Accepted Answer

The image displays a triangle ABC with a point D on side BC and a point E within the triangle.

Segment AD has a tick mark, and segment CD has a single tick mark, indicating that AD is not necessarily equal to CD.
Segment BD has a double tick mark.
Segment AC has a single tick mark.
Segment AB has a tick mark.
Segment AE has a double tick mark.
Segment EC has a single tick mark.
There are no explicit statements of equality between sides based on these markings alone, however, markings on AE and AC might suggest a relationship if they were consistent or if other segments had the same markings.
There are markings on AB and BD (single tick and double tick), and on AE and AC (double tick and single tick). The markings on AD and CD (single tick and single tick) are the same.
There are markings on BD (double tick) and AE (double tick).
There are markings on AB (single tick) and AC (single tick). This implies that AB = AC, making triangle ABC an isosceles triangle.
There are markings on AD (single tick) and CD (single tick). This implies that AD = CD.
There are markings on AE (double tick) and BD (double tick).
There are markings on BD (double tick) and AE (double tick).
There are markings on AE (double tick) and EC (single tick).
There are markings on AE (double tick) and BD (double tick). This implies AE=BD.
There are markings on AB (single tick) and AC (single tick). This implies AB=AC.
There are markings on AD (single tick) and CD (single tick). This implies AD=CD.
There are markings on BD (double tick) and AE (double tick). This implies BD=AE.

An angle is marked as 25° near vertex C, likely representing the angle ∠ACE or ∠BCE, or a part of ∠ACB. Given the arc and the angle marker, it most specifically indicates ∠ACE = 25°.
