(1) Two triangles one similar if
(i) The corresponding sides are in proportion.
(ii) The corresponding angles are equal.
(2) If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.
(3) If a line divided any two sides of a triangle in the same ratio. Then the line must be parallel to the third side.
(4) The midpoint theorem states that the line segment connecting the midpoints of two sides of the triangle is said to be paralle to its third side is also half of the third side.
(5) If the corresponding angles of two triangles are equal, then corresponding sides are proportional then the triangles are similar.
(6) If two angles of one triangle are respectively equal to the two angles of another triangle then the two triangles are similar.
(7) If in two triangle, sides of one triangle are proportional to the sides of other triangle, then their corresponding angles are equal and hence the two triangles are similar.
(8) If one angles of a triangle is equal to 1 angle of the other triangle and the sides including these angles one proportional, then the two triangles one simialar.
(9) In a right angles triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides.
(10) If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then triangle is a right triangle.
(30) (i) True, two circles of any radii are similar to each other.
(ii) False, two rectangles are similar if their corresponding sides are proportions.
(iii) False.
If two triangels are similar then their corresponding angles are equal and their sides are proportional.
(iv) True.
(vi) False.
The polygon joining the midpoints of a quadrilateral is not a rhombus. It is a parallelogram.
