All squares are …………… (similar/congruent).

Are a rectangle and a parallelogram similar. Discuss.

State the reasons for the following. (i) A square is a special kind of a rectangle. (ii) A rhombus is a special kind of a parallelogram. (iii) A rhombus and a kite have one common property. (iv) A square and a rhombus have one common property.

Show that the diagonals of a rhombus divide it four congruent triangles.

If a ,b ,c and u ,v ,w are the complex numbers representing the vertices of two triangles such that c=(1-r)a+r b, and w=(1-r)u+r v , where r is a complex number, then the two triangles (a)have the same area (b) are similar (c)are congruent (d) None of these

I have tied my square bathroom wall with congruent square tiles. All the tiles are red, except those along the two diagonals, which are all blue. If I used 121 blue tiles, then the number of red tiles I used are

Prove that the sum of the squares of the sides of a rhombus is equal to the sum of the squares of its diagonals

Find the area of a rhombus base is 14 cm and height is 9 cm.

Prove that the sum of the squares of the diagonals of rhombus is equal to the sum of the squares of the sides.

If S = {square, rectangle, circle, rhombus, triangle}, list the elements of the following subset of S. The set of shapes which have radius.
