To choose:
One of the following statements to complete the sentence.
“The knowledge that the sum of the measures of angles of a triangle is
- … know because of Figure 7.35 (see page 346).
- … certain, so the foundations of geometry would be destroyed if it were proved false.
- … sometimes used to decide whether the geometry is on a plane, a pseudosphere, or a sphere.”
