Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.

What property does a square have that a rhombus doesnt have?

A square has four right angles, each measuring 90 degrees, which is a property that a rhombus does not necessarily have. While all squares are rhombuses (having all sides of equal length), not all rhombuses have right angles; they can have angles of varying degrees. This right angle property is what distinguishes squares from rhombuses.
