To trisect a right angle, the correct answer is **D. isosceles right** triangle.

### Explanation
When you trisect a right angle, you are dividing the angle, which measures $90^\circ$, into three equal parts, each measuring $30^\circ$. One effective method to achieve this is by constructing an isosceles right triangle.

An isosceles right triangle has two equal angles of $45^\circ$ and a right angle of $90^\circ$. When you place this triangle in a way such that one of the equal angles is $30^\circ$ from the horizontal line, you can effectively create an angle of $30^\circ$ to use in further constructions.

The use of an isosceles right triangle provides a geometrical method to assist in the construction required for trisecting a right angle, as it establishes the necessary angles to achieve the trisection.

Thus, the answer is **D. isosceles right** triangle.
