In triangle PQR,

P,Q,R are the mid points of the sides of triangle ABC. Another triangle is drawn by joining these points. A One dot is placed into the figure without looking into the picture. What is the probability of falling the dot in triangle PQR. What is the probability of falling the dot outside the triangle.

In triangle A B C and Delta PQR shown below. A B=Q R , BC=RP and C A=P Q i) Are CD and PS equal? Why? ii) What is the relation between the areas of triangle ABC and triangle PQR?

ABC is an equilateral triangle with side 10 cm, and AD is the altitude to the side BC. If it cut into two triangles along AD and pieces are joined to get another triangle PQR Find the approximate perimeter of /_\PQR .

ABC is an equilateral triangle with side 10 cm, and AD is the altitude to the side BC. If it cut into two triangles along AD and pieces are joined to get another triangle PQR Calculate the area of /_\PQR .

The vertices of triangle PQR are P(2,1), Q(-2,3) and R(4,5) . Find equation of the median through the vertex R .

Triangle ABC' and 'triangle PQR' 'are similar triangles. If 'AB=6 cm, BC=7 cm, PQ=9 cm','PR=6 cm', find other sides of the triangles.
