I can classify triangles as right triangles based on the measure of their angles and the relationship between their sides.
- 1
A right triangle is defined as a triangle that contains one angle that measures exactly 90 degrees.
- 2
Right triangles are classified based on their angles, and a box in the corner of a triangle typically represents a 90° angle.
- 3
A triangle can only have one right angle because the sum of all angles in a triangle must equal 180 degrees.
