Structurally, triangles are perhaps the strongest of all shapes.
The even distribution of weight among all three sides makes it resilient to breakage and is often relied on by engineers when building a bridge.
A prime example is the Chapel Bridge located in Switzerland, which happens to be the oldest truss bridge in the world that’s still standing and operational.
One of the things Chapel Bridge is best known for is its triangle trusses, which have aided in this historical bridge withstanding the test of time.
Triangles are everywhere in the world around us, from nature to skyscrapers to bridges found around the world.
Below, we have the list of 29 triangle-shaped things for any curious triangle seeker.

Games and Crafts for Learning About Triangles
Identifying basic shapes can be challenging for young learners — especially triangles since there aren’t many naturally triangular things!
Try these fun games and craft ideas to help a child understand triangles better.
- Connect the dots. Draw a series of dots spread out across a blank sheet of paper. Ask the child to connect them to create triangles.
- Choose the triangle. To help children learn to identify triangular-shaped items, present them with several objects of different basic shapes. Make sure some of them are triangular, and ask the child to pick the triangles out of the group.
- Fill in the triangle. Draw a giant triangle on a blank sheet of paper, then choose an age-appropriate medium for the child to use to fill it in. This could be crayons, markers, paint, or colorful bits of paper to glue on.
- Match the shapes. Find pairs of circular, square, and triangular items. (You can also cut the shapes out of paper if you don’t have enough things of different shapes on hand.) Then have the child match the shapes that go together, helping them to practice what each shape is called.
- Go on a scavenger hunt. Help the child look around the room and find items shaped like triangles. Depending on the child’s age, you may want to put a few easy finds in the area.
