What is a right triangle?

• A triangle with one angle equal to 90 degrees.

• A triangle with no angles measuring more than 45 degrees.

• A triangle with all angles equal to 60 degrees.

• A triangle with two equal sides and one angle greater than 90 degrees.

In a right triangle, which angle is 90 degrees?

• The obtuse angle is 90 degrees.

• The acute angle is 90 degrees.
