The construction of triangles is based on the rules of congruent triangles. A triangle can be drawn if-
Construction of a triangle with three given sides (SSS criterion)
Draw a triangle ABC with the sides AB = 6 cm, BC = 5 cm and AC = 9 cm.
Step 1: First of all draw a rough sketch of a triangle, so that we can understand how to go ahead.
Step 2: Draw a line segment AB = 6 cm.
Step 3: From point A, C is 9 cm away so take A as a centre and draw an arc of 9 cm.
Step 4: From point B, C is 5 cm away so take B as centre and draw an arc of 5 cm in such a way that both the arcs intersect with each other.
ABC is the required triangle.
