• in triangle abc, AB=8 cm, AC= 10 cm and angle B is 90 degree. P and Q are points on the sides AB and AC respectively such that PQ = 2 cm and angle PQA is 90 degree. Find area of apq
• A metal beam, AB is 6 metres long. It is hinged at the top , P, of a vertical post 1 metre high. When B touched the ground as shown in figure 1. When A comes down to the ground , B rises , as shown in the figure 2. By calculating the length of AP, or otherwise , find the height of B above the ground. 
• Altitudes BN and CM of triangle ABC meet at age prove that  CN.HM=BM.HN HC/HB =√[(CN.HN)/BM.HM]
  
• In the given figure,PQ || RS || TU,PQ=5cm,TU=7.5cm,RU=a and RS=b T.P:UTR ~PQR and then solve for a and b
  
• What is the length of an altitude of an equilateral triangle with side a.
• Prove that the ratio of perimeter of two similar triangles is proportional to the ratios of  corresponding sides of the triangles
• In triangle ABC, angle ABC is equal to twice the angle ACB, and bisector of angle ABC meets the opposite side at point P. Show that: ¡) CB:BA=CP:PA ii) AB*BC=BP*CA
• Prove.
  
• Plz solve the sum
