Triangle Structure Quiz

What happens if one side of a triangle is pushed?

• The triangle collapses.

• The triangle’s angles change shape.

• The triangle remains rigid unless the side’s length changes.

• The triangle turns into a circle.

What type of force is being applied when you squeeze both ends of a triangle together?

• Tension

• Compression

• Expansion

• Rotation

Which part of a triangle is most responsible for its strength?

• Its color

• Its size

• The fixed relationship between its sides and angles

• The number of triangles in a structure

What is the primary reason triangles are considered stronger than squares or rectangles?

• They have more sides.

• They are easier to construct.

• Their shape cannot change without changing the length of their sides.

• They are lighter in weight.

What happens to a triangle when compression is applied?

• It expands.

• It rotates.

• It pushes on the sides.

• It collapses.

What is the effect of tension on a triangle?

• It compresses the sides.

• It pulls on the sides.

• It changes the angles.

• It shortens the sides.
