Draw line segment AB with length 5.8cm II. At point A, construct a 90oangle using a compass ( perpendicular bisector method) III. From point A, along the line at 90o to AB, measure and mark a length of 4.2cm. label this point C. IV. Connect point B and C to form Δ ABC. Part b Steps of construction I. Draw a line segment LM of length 4cm. II. At point M, construct an angle of 1200 . Extend a line from M at this angle III. From point M along the line just drew, measure and mark a length of 4.7cm. label this point N IV. Connect point N and L to complete the triangle Δ LMN Part c Steps of construction I. Draw a line segment PQ of length 7.2 cm II. At point P, construct an angle of 45o. extend a line from P at this angle III. At point Q, construct an angle 75o in the direction that will intersect the line drawn from P, Extend a line from Q at this angle. IV. The point where these two lines intersect is a point R. connect points R ti P and R to Q to complete the triangle Δ PQR Part d Steps of construction I. Draw a line segment XY of length 5cm II. At point X, construct an angle 300 . Extend a line from X at this angle. III. Since the sun of angles in a triangle must be 180 degree and we already have 300 +1050= 1350. IV. The remaining angle at Y must be 1800- 1350= 45o V. Construct an angle of 45o at Y. VI. The point where the two lines from X and Y intersect will be point Z. VII. Connect Z to X and Y to complete the triangle Δ XYZ Question No 2 Part a Steps of construction I. Draw a line segment AB of length 6.8cm II. At point A, construct a 90oangle using a compass ( perpendicular bisector method) III. From point B, along the line at 90o to AB, measure and mark a length of 8.1 cm. label this point C. IV. Connect point B and C to form Δ ABC. Part B Steps of construction I. Draw a line segment DE of length 5.2cm II. At point E, construct an angle 450 . Extend a line from E at this angle. III. From point D measure and mark a length of 4 cm along the line you just drew. Label this point F IV. Connect point F to point E to complete the triangle Δ DEF Part C Steps of construction I. Draw a line segment QR of length 7.0cm II. At point R, construct an angle 750 . Extend a line from R at this angle. III. With centre at Q draw an arc of radius 5.6 cm which does not intersect RA. IV. Construction of Δ PQR is not possible Part D Steps of construction I. Draw a line segment XY of length 3.8 cm II. At point Y, construct an angle 650 . Extend a line from Y at this angle. III. With X as the center use a compass to draw an arc with a radius of 5cm, which will intersect the line drawn from Y at point Z. IV. Connect point Z to points X and Y to complete the triangle Δ XYZ Part E Steps of construction I. Draw a line segment BC of length 5.7 cm II. At point B, construct an angle 1050 . Extend a line from B at this angle. III. With C as the center use a compass to draw an arc with a radius of 7.5cm, which will intersect the line drawn from B at point A. IV. Connect point A to points B and C to complete the triangle Δ ABC Part F Steps of construction I. Draw a line segment AB of length 6.1 cm II. At point A, construct an angle 300 . Extend a line from A at this angle. III. With B as the center use a compass to draw an arc with a radius of 3.8cm, which will intersect the line drawn from A at point C. IV. Connect point A to points B and C to complete the triangle Δ ABC About This lecture: In this lecture i have solved the following question Chapter: 10 Practical Geometry Exercise: 10.1 Question: 1 & 2 Concept: Construction of angles and triangle Class/Grade 9th Book: Class 9th Math National Book Foundation Publishers: NBF For more lecture:    / @taleemotarbiatkiduniya   Your searches: Grade 9 new book Federal Board grade 9th new syllabus Taleem o tarbiat ki dunya class 9 New model textbook of mathematics grade 9 Grade 9 exercise 10.1 Chapter 10 exercise 10.1 ch 10 ex 10.1 taleem o terbeat ki dunya class 9 Grade 9 maths exercise 10.1 National Book Foundation class 9 chapter 9 exercise 10.1 taleem o tarbiat ki duniya National Book Foundation class 9 ex 10.1 Maths exercise 10.1 class 9 Exercise 10.1 grade 9 Geometry and polygon Equation of straight line line in symmetric form Model textbook of mathematics exercise 10.1 National Book Foundation grade 9 exercise 10.1 Grade 9 chapter 10 Geometry of straight line Grade 9 geometry and polygon exercise 10.1 Grade 9 new syllabus trigonometry For more lecture:    / @taleemotarbiatkiduniya
