Assertion [A] All regular polygons of the same number of sides such as equilateral triangle, squares etc. are similar. |
Reason [R] Two polygons are said to be similar, if their corresponding angles are equal and lengths of corresponding sides are proportional. |

Assertion [A] ABCD is a trapezium with \[DC||AB\]. E and F are points on AD and |
BC respectively such that\[EF||AB\]. |
Then, \[\frac{AE}{ED}=\frac{BF}{FC}\]. |

Assertion [A] In a \[\Delta ABC\], if D is a point on BC such that D divides BC in the ratio AB: AC, then AD is the bisector of \[\angle A\]. |
Reason [R] The external bisector of an angle of a triangle divides the opposite sides internally in the ratio of the sides containing the angle. |

Assertion [A] If in a \[\Delta ABC\], a line \[DE||BC\], intersects AB at D and AC at E, then\[\frac{AB}{AD}=\frac{AC}{AE}\]. |
Reason [R] If a line is drawn parallel to one side of a triangle intersecting the other two sides, then the other two sides are divided in the same ratio. |

Assertion [A] In a rhombus of side 15 cm, one of the diagonals is 20 cm long. |
The length of the second diagonal is \[\frac{AB}{AD}=\frac{AC}{AE}\]cm. |
Reason [R] The sum of the squares of the sides of a rhombus is equal to the sum of the squares of its diagonals. |

Assertion [A] In \[\Delta ABC\], \[\angle B=90{}^\circ \] and \[BD\bot AC\]. If AD = 4 cm and CD = 5 cm, then BD is \[2\sqrt{5}\] cm. |
Reason [R] If a line divides any two sides of a triangle in the same ratio, then the line must not be parallel to the third side. |

Assertion [A] \[\Delta ABC\] is an isosceles, right triangle, right angled at C. Then, \[A{{B}^{2}}=2A{{C}^{2}}\]. |
Reason [R] In a right angled triangle, the cube of the hypotenuse is equal to the sum of the squares of the other two sides. |
