Draw a polygon on a square dot sheet. Also draw it's congruent figures in different directions and mirror image of it.

Draw two congruent figures. Are they similar? Explain

Draw a square on a graph sheet and draw its dilations with scale factors 4 and 5.

Using a square dot sheet or a graph sheet draw a rectangle and construct a similar figure. Find the perimeter and areas of both and compare their ratios with the ratio of their corresponding sides.

Draw ten polygons with different shapes in your note book.

Read the following passage and answer the questions followed by is silicates are a group of minerals which have the general formula SiO_(2) , the most common of which is quartz. Quartz is a frame work silicate with SiO_(4) , tetrahydra arranged in spirals. The spirals can turn in clockwise or anticlock wise direction a feature that results in there being two mirror images opticlaly active varities of quartz. The silicate anion in the mineral kinoite is a chain of three SiO_(4) , tetrahedra that share coners with adjacent tetrahedra. The mineral also contain Ca^(2+),Cu^(2+) ions and water molecules in 1 : 1 : 1 ratio. The mineral is represented as

Draw the following 3-D figures on isometric dot sheet.

Draw a triangle on a graph sheet and draw its dilation with scale factor 3. Are those two figures are similar?

In the following incomplete figures, the mirror line (i.e. the line of symmetry) is given as a dotted line. Complete each figure, performing reflection on the dotted (mirror) line. (You might perhaps place a mirror along the dotted line and look into the mirror for the image). Are you able to recall the name of the figure you complete?

Draw a ray diagram showing the image formation by a convex mirror.
