A problem is not ready to be solved until the creator supplies it with an answer. The solver's answer is considered correct if it matches the creator's (see Overview for details).
To define the answer to the currently open problem, select Answer from the Edit menu. Select the answer type:
Open the Value pane.
Enter a valid expression. Click OK. To minimize the input, have a notepad record selected ahead of time.
The term point set refers to a single point, end points of a segment (2 points) or a path (2 or more points).
Enter one or more labels separated by commas. Click OK. To minimize the input, have the points selected ahead of time in the selected figure.
Reference the plane by 3 comma-separated labels. Click OK. To minimize the input, have some reference elements, such as 3 points, a point and a segment, or a face selected ahead of time in the selected figure.
Unlike a fixed plane, that is a plane occupying a fixed position in space, a condition plane must satisfy a number of conditions. Generally, a condition plane is not unique.
There are three groups of conditions. Select a condition in at least one of the groups. Click OK.
The first group contains the following conditions:
Reference the given point, line or plane, as required, by comma-separated labels. To minimize the input, have the elements selected ahead of time in the selected figure.
The second group consists of the following condition:
Enter a valid expression. The expression will be interpreted as the numerator of a ratio whose denominator is 1. For example, a + 1 means that the volume should be cut in ratio a + 1 : 1. Select a notepad record ahead of time to have it copied automatically to the input box.
The third group refers to the way the plane cuts the figure. The section may be shaped like an:
The answer definition can be undone.
Note that, although, as a rule, the problem creator enters the answer symbolically, Geometria stores all answers numerically. Once entered, the answer will be unaffected by all subsequent actions upon figures. Therefore it is a good idea to (re)enter the answer as a last action before saving the problem and making it available to solvers.
The solver concludes the solution by providing a correct answer. Note, again, that the solver's answer is considered correct if it matches the creator's.
Have the solution opened. Select Answer from the Edit menu. Enter a valid expression or comma-separated labels, as appropriate. To minimize the input, have a notepad record and/or some elements, such as points, segments or a face, selected ahead of time in the selected figure. Click OK.
An evaluation of the answer (corect or incorrect) will pop up.
If the answer is correct, it will conclude the solution log. No more actions will be possible unless the answer is undone. You may want to save the solution to a file. A saved solution can later be played back.
