Understanding Right Triangle Properties

The video tutorial introduces the concept of right triangles, explaining that they have one right angle, denoted by a square in the corner. It discusses the sum of angles in a triangle and the importance of identifying the hypotenuse and legs. The tutorial further explains how to differentiate between adjacent and opposite sides based on the angle of reference, which is crucial for applying the Pythagorean theorem and trigonometry. Understanding these concepts is essential for solving problems involving right triangles.

What is a defining feature of a right triangle?

• It has one obtuse angle.

• It has three acute angles.

• It has one right angle.

• It has two equal sides.

How many right angles can a triangle have?

• None
