Trigonometry Techniques for Triangles

What is the hypotenuse in a right triangle?

• The hypotenuse is the longest side of a right triangle.

• The hypotenuse is the sum of the other two sides in a right triangle.

• The hypotenuse is the shortest side of a right triangle.

• The hypotenuse is the side opposite the right angle in any triangle.

How do you identify a right triangle?

• A triangle with all angles measuring less than 90 degrees.

• A triangle with one angle measuring 90 degrees.

• A triangle with two equal sides.

• A triangle with one angle measuring 180 degrees.
