What is the relationship between the sides and angles of a triangle?

Back

In a triangle, the larger the angle, the longer the opposite side. Conversely, the smaller the angle, the shorter the opposite side.

What is a right triangle?

Back

A right triangle is a triangle that has one angle measuring 90 degrees.

What is the difference between strict and non-strict inequalities?

Back

Strict inequalities (>, <) do not include the endpoints, while non-strict inequalities (≥, ≤) include the endpoints.

How can you represent an inequality graphically?

Back

An inequality can be represented on a number line with an open circle for strict inequalities and a closed circle for non-strict inequalities.
