Plot the triangle on the coordinate plane and use the coordinates to see if the triangle is a right triangle.

Look and see if the triangle looks like it has two perpendicular sides.

You would have to know two of the angles or all three sides to test the Pythagorean theorem.

Draw the triangle and use a protractor to measure the length of the sides and angles.

The correct answer is: You would have to know two of the angles or all three sides to test the Pythagorean theorem.

To determine if a triangle is a right triangle with one 90 degree angle, you can use the Pythagorean theorem. If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle.
