Covalent bond

Answer

$$	riangle P Q R \sim 	riangle C A B$$

Answer

$$	riangle P Q R \sim 	riangle A B C$$

Answer

$$	riangle C B A \sim 	riangle P Q R$$

Answer

$$	riangle B C A \sim 	riangle P Q R$$

Question 2

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.

Question 3

Assertion (A): If a line divides any two sides of a triangle in the same ratio, then the line is parallel to third side.

Reason (R): Line segment joining the mid-point of any two sides of a triangle is parallel to the third side.

Question 4

Assertion (A) : In a $$	riangle A B C$$, if $$D$$ is a point on $$B C$$ such that $$D$$ divides $$B C$$ in the ratio $$A B: A C$$, then $$A D$$ 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.

Covalent bond

Question 5

Assertion (A): If in a $$	riangle A B C$$, a line $$D E \parallel B C$$, intersects $$A B$$ at $$D$$ and $$A C$$ at $$E$$, then $$\frac{AB}{A D}=\frac{A C}{A E}$$

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.
