Question

select the image that fits the description below: two planes intersect at $overline{bh}$.

Explanation:

Step1: Check intersection line in first image

In the first - image, the two planes intersect at line $\overline{AB}$, not $\overline{BH}$.

Step2: Check intersection line in second image

In the second image (the rectangular - prism), the two planes (e.g., the front - face and the side - face) intersect at line $\overline{BH}$.

Step3: Check intersection line in third image

In the third image, the lines shown do not represent the intersection of two planes as $\overline{BH}$ is not an intersection line of two planes.

Step4: Check intersection line in fourth image

In the fourth image, there is only one plane shown with a line $\overline{BH}$ on it, not two planes intersecting at $\overline{BH}$.

Answer:

The second image (the rectangular - prism)
