CBSE Class 9 - Construction of Triangles Videos

• construct a triangle ABC in which BC is equal to 7 cm angle b is equal to 75 and angle b + angle c is equal to 13 cm
• Construct a triangle ABC where BC=5cm,angle B=30°and AC-BC=2cm.
• Construct triangleABC in which AB=5cm,AC–BC=2.5 angle AngleA=30°
• sir you did not teach how to construct triangles with given base,base angle and perimeter
• construct a ?ABC whose perimeter is 10.4cm base angle are 45 and 120
• The perimeter of the triangle is 14.4 cm and the ratio of the length of its side is 2 is to 3 is to 4 construct a triangle
• Construct triangle ABCABC in which BC=5.2cm,  angle B=60 degree,  AB-AC=2.5cm
• Construct a triangle in which BC = 7cm, angle B = 75^o and AB +AC = 13cm.
• Construct a triangle XYZ in which angle Y = 30^o, angle Z = 90^o and XY + YZ + ZX =11cm.
• If two sides of a triangle are unequal, the angle opposite to the greater side will be greater. Prove.
