What geometric shapes are shown and what are their dimensions?

The image displays three triangles. The first triangle, labeled ABC, has sides AB = 4 cm and BC = 3 cm. The second triangle, labeled CDE, has sides CD = 3 cm and DE = 4 cm, and a height of 4 cm from vertex C to the base DE (or from vertex D to the base CE, or from vertex E to the base CD, assuming it's an altitude). The third triangle, labeled PQT, has sides PQ = 1 cm, QT = 2 cm, and PT = 2 cm.
