Isosceles Triangle Bridge Construction

An isosceles triangle was used to construct a bridge with the following measurements:


  • Base: 4 cm

  • Perimeter: 20 cm cube



Finding the Length of the Other Two Sides

Since the triangle is isosceles, we know that the other two sides are equal in length. To find the length of these sides, we need to subtract the base from the perimeter and then divide the result by 2:

(20 - 4) / 2 = 8 cm


Constructing the Bridge

Using the measurements we found, we can construct the bridge. We will need:


  • Two identical pieces of metal or wood that are 8 cm long

  • One piece of metal or wood that is 4 cm long


We can then connect the three pieces together to form an isosceles triangle with a base of 4 cm and two equal sides of 8 cm.

This triangle can then be used to construct the bridge by placing it over a gap or river and securing it in place.


Advantages of Using an Isosceles Triangle

Using an isosceles triangle to construct a bridge has several advantages:


  • It is a simple and efficient design that requires minimal materials

  • It is a strong and stable structure

  • It is easy to construct and can be done quickly


Overall, an isosceles triangle is a great choice for constructing a bridge when simplicity, efficiency, and strength are important factors.

What is the length of the equal sides?
Sol: let x cm bethe length of equal sides of the isosceles triangle so x+x+4=20
2x+4=20
2x=20-4
2x=16
x=16÷2
x=8 cm
