Question

Draw a triangle of sides 4 cm, 5 cm and 6 cm. Draw two different right triangles of the same area.

Answer 1

Answer:

Step-by-step explanation:

Using Heron’s formula to find the area of the triangle

 

s = ½(3+4+6)

 

 = 6.5

 

 

Area = root (6.5)(6.5-3)(6.5-4)(6.5-6)

 

      = 5.33

 

 

The other three triangles are right angled and must have area =  5.33

 

First triangle:

Base = 4, height = 2.8

 

Second triangle:

 

Base = 5, height = 2.1

 

 

Third triangle:

 

Base = 6, height = 1.8
