Analyze the geometric figures in the image, specifically focusing on problems 3, 4, 7, and 8.

Analysis of Geometric Figures:

The image displays four geometric problems, labeled 3, 4, 7, and 8, each featuring triangles with various markings indicating side lengths and angles.

Problem 3:

• Depicts a triangle labeled M, N, and another vertex.
• One angle is marked as 75 degrees at vertex M.
• There are tick marks on two sides of the triangle, suggesting they are equal in length.
• Two lines intersect inside the triangle, forming points A, B, and C.

Problem 4:

• Shows a triangle with vertices A, D, and another vertex.
• An angle at vertex A is marked as 45 degrees.
• There are tick marks on two sides, indicating equal lengths.
• Lines segment AD with point M, and a line segment connecting M to B. Point B also lies on a horizontal line passing through C.

Problem 7:

• Presents a triangle with vertices A, C, and D.
• A line segment from A to B bisects CD, as indicated by the double tick marks on CB and BD.
• The segments AC and AD are marked with single tick marks, indicating they are of equal length.
• A vertical line segment AB is shown.

Problem 8:

• Features a triangle with vertices D, E, and A.
• An angle at vertex E is marked as 70 degrees.
• There are tick marks on sides DE and EA, suggesting they are equal.
• A line segment from A passes through B and C.
• Point M is on side DE.
• There are tick marks on DM and ME, indicating they are of equal length.
• There are tick marks on AD and AE, indicating they are of equal length.
