How many right angles can a triangle contain?
One
Because a triangles total angle measures can only add up to 180 degrees therefore if it had two it would already add up to 180 without the third angle.

A triangle cannot contain any right angles. By definition, a triangle consists of three angles whose sum is always 180 degrees. If one of the angles were a right angle (90 degrees), the other two angles would have to sum up to 90 degrees as well, making the total sum greater than 180 degrees, which contradicts the definition of a triangle. Therefore, a triangle cannot contain any right angles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
