If AB = 8 cm, BC = 15 cm and CA = 19 cm. State whether these sides form a triangle ΔABC.
Yes, they form an right angled triangle
Yes, they form an isosceles triangle
No, a triangle cannot be formed
Yes, they form a triangle as sum of two sides is greater than the third side
AB + BC > CA, BC + AC > AB, AC + AB > BC
In △ABC, sides AB = BC =CA. What is this triangle called?
If the three sides of a triangle are all different lengths, they form an isosceles triangle.
If two sides of a △ ABC are equal in length and the third side has a different length, then the triangle is a/an:
