📚 Topic Summary
In a right triangle, the hypotenuse is the longest side, always opposite the right angle (90-degree angle). The other two sides are called legs. Identifying these parts is crucial for applying trigonometric functions and the Pythagorean theorem ($a^2 + b^2 = c^2$). This practice sheet helps you reinforce this fundamental skill.
