Geometry B, Assignment 1. Symmetry

If l is a line of symmetry, find the figure that is symmetrical by l.

Essentially the answer to this question is repeats of the above graphics, just upside down to form mirror images. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q143a.gif

Name the kind or kinds of symmetry the following figure has: point, line, plane, or none. H

Point Line

Name the kind or kinds of symmetry the following figure has: point, line, plane, or none. O

Point Line

If n is a line of symmetry, find the figure that is symmetrical by n.

The same concept applies here. Since the above graphic is the photo's right half, you need to pair it with the correct left half. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q144b.gif

If N is the plane of symmetry, click on the graphic to find the figure that is symmetrical with respect to plane N.

This question is fairly simple if you comprehend plane symmetry. We have a topmost cone that is stationed as you would normally picture it; bottom half facing down on the plane. In order to complete this, you need the cone that has its bottom half facing upward to form symmetry. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q148a.gif

Click to choose the correct graphic with all the lines of symmetry as defined by a line. (Parallelogram)

Now I know this probably looks like a rhombus, but I assure you it isn't. If it were a rhombus, it would have symmetrical lines since its a special case. Therefore, the answer to this question is 0 lines of symmetry; it is the blank graph. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q133f.gif

Click to choose the correct graphic with all the lines of symmetry as defined by a line. (Hexagonal pyramid)

The answer to this question is the graph with 1 line of symmetry. Its the graph that cuts the pyramid from top to bottom. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q132d.gif

Click to choose the correct graphic with all the lines of symmetry as defined by a line. (Rectangle)

The answer to this question is the graph with 2 lines of symmetry. Its the graph with a line cutting the rectangle vertically and horizontally. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q131d.gif

Click to choose the correct graphic with all the lines of symmetry as defined by a line. (Square)

The answer to this question is the graph with 4 lines of symmetry. Essentially, its the graph with the most lines on the square; hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/q130a.gif

If P is a point of symmetry, click on the graphic to find the figure that is symmetrical by P.

With this question, the answer is a line at the bottom, but in the middle. Hope this is clear enough. https://cdn.lti.glynlyon.com/media/eb614976-0183-42d4-ae39-f5e68301ec13/img/groupi21.gif
