请将图片中的数学题做出讲解视频---**Question Number:** 24.
**(Total score 12 points)**
**Problem Description:**
As shown in the figure, in Right Triangle ABC, ∠ACB=90°, D is the midpoint of AB, E is a moving point on BC (not coinciding with endpoints B, C). Connect AE intersecting CD at point F. A circle passing through points E, F, D intersects BD at point G (not coinciding with B, D). Connect EG.
**(1) If CE=CF, ∠B=50°, find the measure of ∠EGD:**
**(2) If $\frac{CE}{BE} = \frac{1}{2}$, find the value of $\frac{EF}{AF}$:**
**(3) Prove: EG+EF=AF.**
**Diagram Description:**
* **Type:** Geometric diagram illustrating a right triangle and a circle.
* **Main Elements:**
* Triangle ABC, which is a right triangle with the right angle at vertex C.
* Point D is on the hypotenuse AB and is labeled as the midpoint.
* Point E is on the side BC, between B and C.
* Segment CD is drawn from C to D.
* Segment AE is drawn from A to E.
* Point F is the intersection of segments AE and CD.
* A circle passes through points E, F, and D.
* This circle intersects the segment BD (part of AB) at point G.
* Segment EG is drawn.
* Points A, B, C, D, E, F, G are labeled.
* **Angles:** ∠ACB is indicated as a right angle. ∠B is shown.
* **Annotations:** The diagram is labeled as being for Question 24.
