  • Our topic is Trigonometry 
  • Lets see the length and height of this monument . how can we find it?by trigonometry you can find the height of this monument
  • Height
  • Remember its always easier to find a distance on the length on the ground than finding the distance vertically and we can find approximate measure of this angle which is theta.
  • Three are six trigonometric ratios in the trigonometry . but now we are going to study only 3 
  • with just these two pieces of information we can find the height of this monument . lets go back to our class .
  • Distance
  • Ø
  • Height
  • Trigonometry is the study of relationships between sides and angles of a triangle
  • what is trigonometry In Greek tri - Threegon - sides metron - measure
  • A right angle triangle which is also refereed as right triangle . this right triangle is right angle at this vertex . the good news is that one angle is known and only two remain . let the remaining any one angle be theta.so angle A would be theta .
  • Side opposite to 90* of a right angled triangle is hypotenuse Side opposite to theta or angle Aside adjacent to theta or angle A 
  • 90*
  •  θ
  • C
  • A
  • vertex
  • B
  • who discover trigonometry? 
  • Hipparchus
  • sinθ= opp/hyp=sine cosθ=adj/hyp= cosinetanθ=opp/adj=tangent
  • hyp
  • adj
  • opp
