Pattern for Figure Completion

Geometry

The figure may be broken into circles, triangles, quadrilaterals, polygons, etc. that overlap, touch each other, enclose some shape(s) or are just parts of the figure.

Illustration 5

Identify the figure that completes the pattern.

Each quarter of the triangle consists of 2 right angled triangles. Thus, option D is correct.

Illustration 6

Identify the figure that completes the pattern.

The missing section should have 4 lines. One of these lines should touch the bottom left of the square and another should touch the top right. Only (D) matches these requirements.
